Is your space haunted by annoying echoes, distracting noise, or unclear sounds? We've been there too. Acoustic problems in any space can disrupt your plans and peace of mind.

 

Think of sound as a naughty kid at your party - sometimes it is too loud, sometimes it is too timid and doesn't want to interact with the others, and it never quite behaves as it should. That’s where acoustic panels come in, but even they aren’t without their quirks.

 

Use this guide to understand the common issues with your acoustic panels and, more importantly, to understand how to solve them. From poor placement to aesthetic conflicts, we’ll walk you through each problem and offer practical, expert-approved solutions to help you reclaim control of your space’s acoustics.

Common Acoustic Issues in Residential Buildings

Poor acoustics in a room can result from several factors, including the room's shape, construction materials, and furnishings. Common acoustic defects such as echo, reverberation, and sound leakage occur when sound waves reflect off hard surfaces or escape through gaps and cracks. For instance, rectangular rooms with hard surfaces like glass or concrete tend to create excessive echo, while rooms with uneven surfaces can lead to sound distortion.

 

Architectural design, construction materials, and the layout of a building significantly impact its acoustics. Buildings with high ceilings, hard floors, and large glass windows often suffer from excessive reverberation, while those with thin walls may experience significant sound leakage between rooms. These issues can compromise privacy, productivity, and comfort in both residential and commercial settings.

Acoustic Panel Limitations and Challenges

While acoustic panels are highly effective at absorbing sound, they are not without limitations. Here is what to have in mind before installing your acoustic panels so that the result won't disappoint you:

  • Frequency Absorption: Not every panel will solve every acoustic need of yours. Not all panels are equally effective across the full range of sound frequencies. Some are better at absorbing high frequencies (like speech), while others are more suited to low frequencies (like bass sounds). Therefore, it's crucial to define precisely the purpose of the acoustic treatment you desire, and next, to properly combine different types of acoustic panels. And yes, we can help you with that!
  • Aesthetics: Acoustic panels can sometimes clash with the existing decor, especially if their design does not match the room’s aesthetic. Luckily, we have a variety of options, including colours and materials, so that you can find the right interior design combination.
  • Maintenance: Over time, acoustic panels can accumulate dust and dirt, which may affect their performance and appearance. Regular cleaning and maintenance are required to keep them in top condition. Good news - all of our acoustic panels are low-maintenance and easy to clean.

How Long Do Acoustic Panels Last?

The lifespan of acoustic panels largely depends on the material, quality, and installation environment. High-quality panels can last for decades if properly maintained, while cheaper options may degrade faster. Environmental factors such as humidity, temperature changes, and exposure to direct sunlight can also affect the durability of acoustic panels. Make sure to use relevant acoustic panels for the different spaces.

 

One good example is the usage of our wood wool acoustic panels in SPA centres and indoor pools. These panels thrive in humid environments while eliminating the well-known annoying echo of such places.

Should I Cover All Walls with Acoustic Panels?

Not necessarily. The key to effective acoustic treatment is strategic placement rather than total coverage. For example, focusing on the first reflection points - areas where sound waves first hit walls - can significantly reduce echo and reverberation without needing to cover every surface. Over-treatment with panels can lead to an overly dampened room, which might make it feel lifeless or dull.

Common Problems with Acoustic Panels

Problem #1: Uneven Sound Distribution

Possible Reason: Incorrect Placement of Panels

 

Improper positioning of acoustic panels is a common issue that can render them ineffective. Placing panels too high on the walls or in areas where sound does not reflect can reduce their ability to absorb sound effectively.

 

It’s essential to identify primary reflection points and areas with the most noise impact to ensure maximum efficiency.

 

Solution: Position panels at ear level on the walls, where sound reflections are most prominent. In-home theatres or studios, ceiling hanging baffles should be placed above mixing or listening areas to capture sound waves effectively. Aim for at least 30% coverage density of the total ceiling area.

Problem #2: Minimal Improvement in Acoustics

Possible Reason: Insufficient Coverage

Insufficient coverage occurs when the acoustic treatment does not cover enough of the room’s surfaces to significantly reduce sound reflections and reverberations.

 

Acoustic panels are effective only when they are strategically placed in sufficient quantities. If too few panels are used or they are only placed in one area, the overall impact on sound quality is minimal.

 

In large or high-noise environments, inadequate coverage will fail to address the acoustic issues, leaving parts of the room untreated and maintaining problematic echoes and sound reflections.

 

Solution: If there are too few panels or they are too small, they won’t absorb enough sound waves, leading to limited acoustic improvement. To achieve better sound control, aim to cover at least 15-30% of the total wall surface area, depending on the room's size and use.

 

Larger or noisier rooms may require greater coverage. Assess the specific acoustic needs of your space and adjust panel placement and coverage accordingly for optimal results.

Problem #3: Inconsistent Sound Absorption

Possible Reason: Material Incompatibility

 

Different acoustic panel materials have unique sound absorption characteristics, which means that using the wrong material can lead to ineffective sound treatment.

 

Foam panels are excellent for high-frequency noise but may not perform well in absorbing low frequencies. When materials are chosen without considering the room's acoustics and the type of sound issues present, the result is often inconsistent sound absorption.

 

Solution: Different materials have varying sound absorption properties. Choosing the wrong material for your acoustic panels can lead to inconsistent sound absorption.

 

Select materials that match the acoustical needs of your environment. Fabric-wrapped panels are ideal for office spaces due to their balance of absorption and aesthetics, while foam panels may be more suited for a home studio.

 

Always consider the specific use and desired acoustics of your space when selecting panel materials.

Problem #4: Reduced Acoustic Performance

Possible Reason: Poor Maintenance

 

Over time, acoustic panels can accumulate dust, dirt, and even mould in humid environments, which can degrade their performance and appearance.

 

Solution: Regularly clean panels using a vacuum with a brush attachment or a damp cloth for fabric panels. In environments prone to high humidity, consider using moisture-resistant panels or adding a dehumidifier to the room.

 

Luckily, all of our acoustic panels are extremely easy to maintain and are ready to serve you for decades.

Problem #5: Overly Damped Sound

Possible Reason: Overuse of Panels

 

Overusing acoustic panels can lead to an overly dampened environment, resulting in a space that sounds flat and lifeless. This problem occurs when too many panels are installed without consideration of the room's natural acoustics, absorbing not only unwanted noise but also desirable sound qualities.

 

Such excessive dampening can strip the room of its natural resonance, making it uncomfortable or unnatural for its intended use, whether it’s for music, conversation, or relaxation.

 

Solution: Using too many acoustic panels can overly dampen a room, making it sound lifeless. To avoid this, use only the amount of treatment necessary to achieve your desired sound quality.

 

A balanced approach is key - conduct sound tests and experiment with different configurations to find the perfect balance that enhances the acoustics without over-damping.

Problem #6: Panels Detaching from Walls or Ceilings

Possible Reason: Improper Installation

 

Incorrect installation can compromise the effectiveness of acoustic panels. Panels that are not securely mounted can fall, causing damage and reducing their sound absorption capabilities.

 

Using inadequate adhesive or mounting hardware is a common reason for acoustic panels detaching from surfaces. This can occur due to the weight of the panels or the type of surface they are being mounted on. If the adhesive or hardware isn't rated to hold the panel securely over time, panels may fall, reducing their effectiveness and potentially causing damage.

 

Different surfaces, such as painted drywall, concrete, or wooden walls, require specific mounting solutions to ensure that panels stay in place and function properly.

 

Solution: Acoustic panels that are not mounted with the appropriate adhesive or hardware can detach from surfaces, reducing their effectiveness and posing a safety risk.

 

Use high-quality, manufacturer-recommended mounting materials and the provided installation guides to ensure panels stay securely in place. For heavy panels or installations on ceilings, additional supports or brackets may be necessary to maintain stability and sound absorption performance.

 

If you are not feeling like a DIY enthusiast today, you can always contact our professionals to install your panels, especially in complex spaces or large installations.

Problem #7: Limited Sound Absorption Range

Possible Reason: Lack of Panel Variety

 

When only one type of acoustic panel is used, the sound absorption is often limited to a narrow range of frequencies. Different materials and panel designs are required to absorb low, mid, and high frequencies effectively.

 

A lack of variety in panel selection can result in certain frequencies not being absorbed, leaving some sound issues unresolved. This limitation can affect the overall sound quality in a space, failing to provide a comprehensive acoustic result.

 

Solution: Using only one type of panel can limit the range of frequencies absorbed, leading to poor overall sound quality. To improve sound absorption across a broader frequency range, combine different types of acoustic panels.

 

Use a mix of bass traps, diffusers, and mid to high-frequency absorbers to address the full spectrum of sound. This combination ensures comprehensive acoustic treatment, enhancing the sound experience in the room.

Additional Problems to Watch For

Beyond the most common issues, there are a few less obvious problems with acoustic panels that can still have a noticeable impact on performance and aesthetics. Being aware of them helps you maintain both the function and the look of your installation:

  • Fading or discolouration over time – Especially in rooms with direct sunlight, fabric-covered panels can lose their colour vibrancy. This doesn’t just affect aesthetics – UV exposure can also slightly alter the fabric’s acoustic permeability.
  • Fabric wear or fraying – In high-traffic areas or spaces where panels are frequently touched, fabrics may start to fray, snag, or develop a worn look. This can shorten the panel’s usable lifespan.
  • Moisture damage – In humid environments, such as basements or coastal locations, panels can absorb moisture, leading to warping, mould growth, or a change in acoustic performance. For such areas, select panels specifically created for a humid environment, for example, wood wool acoustic panels.
  • Damage during cleaning – Using harsh chemicals, abrasive tools, or excess water can degrade panel fabrics or alter the surface texture, affecting both absorption and visual appeal.
  • Attracting dust and allergens – Some fabric textures tend to gather dust, pollen, and airborne particles. Over time, this build-up can dull the surface and impact air quality if not cleaned properly.

Improving Room Acoustics in Specific Settings

To effectively address acoustic issues, it’s crucial to diagnose the problem correctly and apply the right solution. For example, if a room suffers from excessive echo, adding more panels or using panels designed to absorb specific frequencies can help.

 

Start with a sound analysis to identify the room's problematic areas. Adjust the number and placement of panels based on this analysis. In many cases, adding bass traps in corners can significantly improve low-frequency absorption, while wall panels can manage mid to high frequencies.

Don't forget that different environments have unique acoustic needs. For example:

  • Home theatres: Require a balanced mix of sound absorption and diffusion to create an immersive sound experience without deadening the room.
  • Offices: Need to reduce background noise to enhance concentration and privacy, typically using ceiling baffles and wall panels.
  • Restaurants: Must manage background noise to create a pleasant dining experience, often employing a combination of ceiling and wall panels.

What Makes a Good Acoustic Panel?

A good acoustic panel effectively absorbs sound across a broad range of frequencies and is durable, aesthetically pleasing, and easy to install. Key characteristics to consider include:

  • Material: High-density materials such as wood or wool are excellent at absorbing sound.
  • Thickness: Thicker panels generally provide better sound absorption, especially at lower frequencies.
  • Design: Panels should complement the room's aesthetic, with options ranging from fabric-covered to perforated wood designs.

Good acoustics result from a combination of effective sound insulation, absorption, and diffusion. Buildings with good acoustics typically have well-designed room layouts, appropriate use of materials, and strategic placement of acoustic elements.

 

While acoustic panels are effective for improving room acoustics, it's important to start with soundproofing of walls, floors, or ceilings to significantly reduce airborne and impact noise.

Why does the same volume feel soothing at one moment and unbearable at another? A steady 45 dB rainfall can lull you to sleep, while a 45 dB dripping tap at 3 a.m. can keep you wide awake. Volume matters, but your reaction is shaped far more by context (where and when you hear it), predictability (how stable the pattern is), and meaning (what your brain thinks the sound represents).

You might not be a cyborg (yet), but your auditory system is a prediction engine. It continuously forecasts the next fraction of a second and then checks the incoming sound against that forecast.

The Body Shifts From Calm to Vigilance

Any environment that you feel comfortable in, like at home or an office, has certain background noises that your brain can get used to. As soon as a random car honks, there is your cortisol spike.

Stable, low-information sounds align with expectations, so the brain relaxes and shifts toward a slower heart rate and calmer breathing. Intermittent or information-rich sounds (such as horns, door slams, or a partner’s phone buzzing) violate predictions.

Two additional variables in the acoustic profile tilt the experience toward calm or stress:

  • Control: Sounds you can start, stop, or adjust to your liking feel safer than those imposed on you.
  • Relevance: A faint baby cry or an email ping linked to work carries meaning that elevates arousal, even when the dB meter reads low.

Our brains do not evaluate loudness in isolation. They evaluate the pattern, the timing, the frequency content, and the story the sound tells. That is why birdsong can feel restorative during a morning walk yet intrusive at 4:30 a.m. outside your window.

How Your Brain Decides: From Vibration to Emotion

A sound begins as air pressure changes. Your inner ear turns those vibrations into neural spikes that ascend through the whole hearing system. Each relay filters and refines timing, intensity, and spectral cues, so by the time signals reach the cortex, they already carry “where” and “what”, so your brain can act on them in milliseconds.

Predictive Hearing: The Brain is Forecasting

Your auditory system does not wait passively for input. It runs internal models that forecast the next sound, then compares the prediction against reality. When input deviates, a “prediction error” is raised, which you experience as something salient or surprising.

In hearing research, this framework helps explain why an odd tone in a regular sequence can trigger an automatic response even without actively paying attention. That predictive-coding account links small surprises to measurable brain signatures and to the feeling that a noise “sticks out.” 

That is why when we scope a space, it's not enough to only measure the noise levels. We also have to understand what is the type of noise, who the listener is, and what is the whole context of that space. 

Salience And Threat Appraisal: Why Meaning Beats Volume

After early processing, sounds are appraised by networks in the brain that decide “does this matter.” The salience network helps switch the brain toward action when a stimulus is behaviorally relevant, while limbic structures like the amygdala tag affective value.

A distant siren may be quiet, yet very noticeable, because it signals potential danger. Conversely, a louder but predictable fan hum is often ignored because it carries low danger.

Arousal Pathways: From Appraisal to Body Response

If a sound is flagged as important, noradrenaline ramps up, increasing alertness and tightening attention. That arousal couples to the autonomic nervous system: sympathetic activity raises heart rate and vigilance, while parasympathetic activity supports calm and recovery.

Chronic exposure to unpredictable noise leads to a higher stress load across the day. That is why effective soundproofing is a direct investement into ones health. 

Your reaction to a sound reflects rapid loops between prediction, meaning, and physiology. Predictable, low-danger sounds are easy for the brain to model and ignore. Unpredictable or meaningful sounds generate prediction errors, pushing the body toward stress.

What Makes a Sound Calming

Not all “quiet” feels the same. Sounds that relax you tend to be steady, predictable, and low in sharp detail, so your brain does not need to keep scanning for meaning or danger. Calming soundscapes lower arousal because they are easy to forecast and contain no urgent cues.

Sounds That Soothe

The acoustic profile of the sound you are hearing has a direct relation to how you would perceive it. Some sounds can truly soothe:

  • Stable loudness with slow, gentle changes over time
  • Few high-frequency spikes (no clicks, clinks, or squeaks)
  • Low information load (no lyrics or speech to track)
  • Balanced spectrum that avoids harsh highs and booming lows

Rain, surf, and wind often help because they create a broadband, even “bed” of sound. The micro-variations are natural and easy to predict, so the auditory system can down-regulate attention. Allowing your home to become a comfort zone once more. Your brain does not detect alarms in these textures, which lets the parasympathetic system step in and settle heart rate and breathing.

 

a soothing home environment

 

Pink Noise vs White Noise

Masking noise is not exactly like soundproofing, but in a pinch, it can get the job done. Lowering the surprise element of sharp noise would help you have a more stable sleep. 

  • White noise carries equal energy per Hz and can sound hissy to many ears.
  • Pink noise tilts energy toward lower frequencies and tends to feel rounder and more comfortable for sleep or focus.
  • Practical rule: begin at the lowest level that masks the intrusions you notice, then fine-tune. Louder is not automatically better.

Evidence aligns with this picture. Controlled studies show nature soundscapes can speed stress recovery and improve attention compared with urban noise. Periods of silence and slow, stable sound fields are associated with calmer breathing and heart rate, consistent with parasympathetic activation.

Public-health guidance also underscores the role of a quiet night environment for sleep continuity, with recommendations that keep night levels low enough to avoid awakenings from intermittent events.

How to Use This Tonight

Getting a good night's sleep is essential for our health. Luckily for you, we have prepared tips that you can use right away. 

  • Prefer steady, broadband sources (rain, surf, pink noise) over variable sources (music with vocals, podcasts).
  • Keep the contrast in check. If intrusions peak around 50 dB, a masker near 42–45 dB often works because it smooths the difference.
  • Choose non-semantic audio so your brain can ignore it rather than follow it.
  • If a recording contains sudden cymbal hits, door slams, or birds with sharp chirps, try a softer alternative or a gentle EQ roll-off of highs.
  • Almost all streaming platforms have soothing rain sounds. You can even turn on a desk fan.

When “Positive” Sounds Turn Stressful (Birdsong Included)

A sound that feels calming at noon can feel intrusive at 5 a.m. Your reaction depends on context, predictability, and what the sound means to you in that moment. The brain does not rate sounds by volume alone. It asks: “What is it, and do I need to act?”

Context Shifts The Label From Soothing to Stressful

  • Time of day: During the early morning, you spend more time in lighter sleep stages. Smaller stimuli trigger brief awakenings more easily than in deep sleep.
  • Sense of control: Sounds you can stop or anticipate feel safer. Uncontrollable sources (for example, a neighbour’s balcony chat) sustain vigilance.
  • Goal interference: If the goal is sleep, any novel signal that hints at “time to engage” competes with that goal.

Intermittency and novelty matter more than many realise. The auditory system continuously predicts what comes next. When an unexpected event breaks the pattern, the cortex flags a prediction error, and the brainstem can trigger a micro-arousal.

That is why intermittent events such as a single shout, a siren burst, or a sharp bird call are more disruptive than a steady hum at the same average level.

Meaning And Memory Can Flip a “Nice” Sound Into an Alarm

  • Through associative learning, a cheerful chirp that repeatedly precedes unwanted wakeups becomes tagged as relevant.
  • Salience and threat networks bias attention toward biologically meaningful cues, so “what it predicts” matters more than absolute loudness.

At dawn, birdsong often has sharp onsets and irregular spacing. In a quiet bedroom that creates high contrast. The high-frequency edges and variability keep prediction errors elevated, which prevents habituation. The same pattern that feels restorative on a daytime walk can feel like a summons at 5 a.m.

Individual Differences Raise Sensitivity

  • Trait anxiety or insomnia: Higher baseline arousal lowers the threshold for orienting responses. People with insomnia show stronger reactivity to neutral sounds at night.
  • PTSD: Hypervigilance and elevated tone increase startle and reduce the ability to ignore benign stimuli.
  • Sensory sensitivity: Central gain can amplify perceived loudness, so modest sounds feel intrusive.

The practical takeaway is simple: calm the nervous system and the soundscape at the same time. Reduce contrast and novelty, create predictable bedtime cues, and restore a sense of control. Your brain learns the pattern “safe and off duty,” which makes even imperfect environments more sleep-friendly.

 

a mystic looking of myths and truth

 

Myth vs Reality

Silence is not a universal sedative, and sound is not a universal threat. Your nervous system evaluates patterns, timing, and meaning, then decides whether to relax or mobilise. Here is where common beliefs miss the mark.

Myth: Quiet Equals Relaxing

Quiet can help, but it is not automatically soothing. In very silent settings, some people notice tinnitus or intrusive thoughts, which raises arousal. Others sleep better with a low, steady backdrop that masks little spikes in noise.

Evidence suggests stable sound fields and silence can both lower arousal, depending on the person and context (Bernardi et al., 2006; WHO Night Noise Guidelines, 2009).

Myth: Any Nature Sound is Calming

Often true by day, not guaranteed at 5 a.m. Birdsongs, water, and wind tend to carry low informational load and gentle modulation, which aids recovery after stress (Alvarsson et al., 2010).

At dawn, the same birds can produce sharp, intermittent calls that create prediction errors and micro-arousals during light sleep.

Myth: It Is Only About Decibels

Two sounds with the same average level can feel very different. What drives reactivity is the combination of:

  • Spectrum (low frequencies rattle surfaces; high-frequency feel “sharp”).
  • Timing (peaks, onsets, and amplitudes are more disruptive than steady states).
  • Meaning (sirens, alarms, a known door click carries priority in the brain).

This is why night guidelines weigh maximum event levels and number of events, not only nightly averages.

Falling Asleep in Loud Places, Like a Child at a Wedding

Several mechanisms make this possible:

  • Homeostatic sleep pressure: After long wakefulness or high activity, the drive to sleep is strong enough to override moderate noise.
  • Predictability and safety: A steady party murmur can function like broadband masking. If the environment feels safe and the pattern is consistent, the brain stops flagging it as relevant.
  • Developmental and individual differences: Children can show robust sleep pressure and different sensory gating; adults vary in trait arousal, anxiety, and prior learning, which shifts thresholds for awakening.
  • Circadian phase: If noise occurs near the biological low point, sleep onset is easier despite higher dB levels.

Your reaction to sound depends on the brain’s interpretation, not volume alone. Reduce contrast and unpredictability, keep cues consistent, and support a sense of control. Those ingredients make even imperfect soundscapes feel restful.

You've probably come across the term "decibels (dB)" even if you're not a sound engineer or musician. Understanding this concept is not only crucial for how we experience sound, but it can also empower you to upgrade your audio mastery. Are you ready to navigate various scenarios to enhance your acoustic knowledge?

Let us answer some burning questions and offer tips and advice to take your audio game to the next level.

 

The Fundamentals of dB

Decibels (dB) are used to measure how loud a sound is. It's a special way of measuring because each increase of 10 dB means the sound is 10 times more intense. This is helpful because it allows us to measure sounds that are very quiet, like a whisper, all the way up to really loud sounds, like a jet engine. For example, normal conversation is around 60 dB, while a loud rock concert can be over 120 dB. People who work with music and sound need to understand this scale so they can effectively control and manipulate sound.

 

This chart gives a sense of how loud different everyday sounds can be, providing useful reference points for understanding decibel levels in various environments

The best volume for sound depends on what you are doing. For music production, most experts suggest keeping the average volume between -14 dB and -12 dB RMS. This range keeps the sound clear and detailed without causing listener fatigue, allowing producers to focus on the nuances of each track. When mixing or mastering, staying within this range ensures there is enough headroom for further processing and prevents unwanted distortion. At live concerts, sound levels usually range from 85 dB to 105 dB, creating an exciting and immersive experience for the audience. However, it's important to protect your hearing, as prolonged exposure to high volume can cause permanent damage. Using ear protection or taking breaks can help minimise risks. These guidelines help keep the sound enjoyable and safe, whether you are creating music in a studio or enjoying it at a live event.

dB in Music: How to Understand and Use Them

Understanding dB in music is all about realising how different volume levels can affect how the music sounds and how we perceive it. Lower volume levels can add a nice touch of nuance and excitement to a piece of music, while higher volume levels can make the music sound more powerful and intense. Musicians and sound experts use special tools to keep an eye on these volume levels and make sure they're just right so that we can have a great listening experience. Here are some useful tips for managing volume levels in music:

  1. Use a Decibel Meter: Regularly monitor sound levels to avoid exceeding safe thresholds.
  2. Make Sure to Soundproof Properly: Don't forget about the peace of the others around you while keeping your audio game on top.
  3. Employ Compression Wisely: Compression can help manage dynamic range, preventing peaks from becoming too loud.
  4. Balance Instruments: Ensure all instruments and vocals are balanced within the mix to maintain clarity and prevent any single element from overpowering the rest.

 

Noise Measurement Kits and tools for noise control

 

Safe Listening Practices

Listening to music at safe volume levels is really important to take care of your hearing. It's recommended to keep the volume below 85 dB if you're listening for a long time. Did you know that loud sounds can impact your body? Within the first hour of being exposed to really loud noise over 90 dB, your body immediately reacts. The sensitive parts of your inner ear, like the hair cells that help you hear, get stressed out by the intense sound waves. This can cause temporary changes in how well you hear and can even increase your stress levels.

Sounds over 85 dB can harm your hearing over time. For example, personal music players at full blast can go over 100 dB. It's important to know about these noise levels and take steps to protect your hearing, like using volume limiters on your devices and taking breaks from listening to loud music.

The 3 dB Rule

The 3 dB rule is an important concept in sound and music technology. It means that when you increase the volume by 3 dB, the sound's power doubles. This rule is useful for adjusting volume levels and making sure that the sound is consistent in different places. For instance, if you turn up the volume on a speaker system by 3 dB, it will need to use twice as much power.

Common Questions About dB

Is 70 dB Music Too Loud?

Listening to music at a volume of 70 dB is generally safe and comfortable for most people, similar to the background music in a restaurant or a regular conversation. However, everyone's sensitivity to sound is different, so always listen at a level that feels comfortable for you.

What dB Should I Normalise Audio To?

When you're working with audio, normalising it usually means adjusting the volume to make sure it sounds good without being too loud or distorted. For streaming platforms, they recommend setting the loudness level to -14 LUFS (Loudness Units Relative to Full Scale) to make sure that all songs play at a similar volume. This helps make the audio sound consistent and professional.

Protecting Your Hearing

Safe dB levels for the ears are generally considered to be below 85 dB. Lengthy exposure to levels above 85 dB can lead to hearing damage. To protect your hearing, use decibel meters or smartphone apps to monitor sound levels in your environment. Here are some additional tips to protect your hearing:

  • Take Regular Breaks: Give your ears a rest during long listening sessions. We know it's somehow hard when you are in the flow. However, think in the long run and don't compromise on your health in general.
  • Use Ear Protection: In loud environments that you cannot control and apply soundproofing, use earplugs or noise-cancelling headphones. Did you know which is the loudest profession in the world? SPOILER ALERT: Aircraft Maintenance Engineers. They work in airport areas like maintenance hangars, runways, and taxiways. They are exposed to noise levels from 120 to 140 dB. This is like the noise of a jet engine during takeoff.
  • Limit Exposure: Reduce the time you spend in noisy environments whenever possible.
  • A Side Note: Studies show that using earplugs for a long time can cause discomfort, ear infections, and even hearing loss. Although they are handy, they also need replacing often and can't be shared, leading to more costs and waste. Earplugs give temporary relief. So you'd better think long term and consider proper soundproofing and acoustic treatment.

What dB Level Should a Song Be?

A well-mixed song should have an average level of -14 dB to -12 dB RMS, with peaks no higher than -1 dB. This range ensures clarity, dynamics, and a pleasant listening experience across different playback systems. Properly balanced audio not only boosts the listening experience but also preserves the integrity of the music.

We know everyone has THIS ONE SONG you can't help but put the volume on max. It's fine as long as the song is not on repeat too often.

Recognising When Music is Too Loud

Music can be too loud if it makes your ears uncomfortable, causes ringing, or makes it hard for you to hear after you're done listening. You can use a special tool called a decibel meter to check how loud the music is. If the meter shows that the sound level is higher than 85 dB, it's a good idea to lower the volume or take breaks.

The best volume for good sound quality is one that sounds clear, has all the musical details, and is comfortable for the listeners. When creating music, try to aim for an average volume level between -14 dB and -12 dB RMS. In live settings, make sure the sound is loud enough to make an impact, but not so loud that it causes distortion or hurts people's ears. It's all about balance.

Fun Facts and Additional Tips

  • Did You Know? The loudest sound ever recorded was the eruption of Krakatoa in 1883, which was measured at 310 dB.
  • Did You Know? Sound can shape our perception of time. Studies show that people tend to overestimate time duration when exposed to a faster rhythm and underestimate it with a slower rhythm.
  • Pro Tip: Always use high-quality audio equipment and maintain it well to ensure accurate sound reproduction and avoid unnecessary increases in volume to compensate for poor sound quality.

Remember, dBs are really important in music and audio. They can affect how good the sound is and how safe it is for your ears. By knowing about and controlling the volume levels, you can make sure the sound is great and protect your hearing. It doesn't matter if you're a sound engineer, a composer, a live-stage performer, or just love sound; understanding decibels is super important to make sure everything sounds just right.

Walk into any classroom mid-lesson, and you’ll likely hear more than just the teacher’s voice. Chairs scrape, students murmur, some other class has a PE lesson, HVAC systems hum, and footsteps echo from the corridor. Individually, none of these sounds seem catastrophic. But collectively, they create a cognitive minefield, one where attention fractures, memory falters, and learning becomes unnecessarily hard.

A classroom can quickly become a jungle of sounds, kicking learning out the window. Soundwaves need to be tamed. Not by an Australian with a cowboy hat and a dangerous habit of jumping on a croc's back, but an acoustician. Cowboy hat remains an option. 

Why Classroom Acoustics Can’t Be Ignored

In education, we rightly focus on curriculum, teaching methods, and digital tools. But the physical environment in which students learn remains one of the most overlooked variables. Sound is at the centre of that. Just as lighting affects vision and layout affects movement, acoustics directly shape how well students can focus, process speech, and retain information.

From a scientific standpoint, this isn’t abstract. According to cognitive load theory, the brain can only process so much at once. When students strain to interpret muffled speech, their working memory is hijacked by effort, leaving less capacity for actual comprehension.

And the impact isn’t spread evenly: students with hearing loss, auditory processing issues, ADHD, or for whom the main language in school isn’t a native one are disproportionately affected by poor acoustic conditions.

In noisy, reverberant spaces, even the best teachers are fighting against the architecture. But in a well-treated room, every word lands clearly, every question is heard, and every learner gets a fairer shot. And noisy students who interrupt the lesson are easily seen.

Common Acoustic Problems in School Buildings

School buildings are often designed with durability and space efficiency in mind. Not so much for acoustics. For some reason, no one thinks about the behaviour of sound. The result? Learning environments that echo, distract, and fatigue both students and teachers. Very unpleasant, but fixable. 

Outdated Architecture and Hard Surfaces = Echo Chambers

Many older schools were constructed with solid brick walls, tiled floors, and high ceilings, materials chosen for longevity, not sound performance. These hard, reflective surfaces create what’s known as excessive reverberation time: sound bounces rather than fades, making speech muddy and indistinct. Think of it as if you have thrown a hundred rubber bouncy balls with the speed of sound. Chaos. 

Even brief instructions like “Open your books to page 12” can become acoustically smeared, forcing students to mentally reconstruct what they just heard. The younger the student, the harder this becomes. And keep in mind that students get instructions for hours every day. Maybe the first time the echo can be ignored, but at hour 7, or 8? The fatigue grows and grows, and learning capability dwindles. 

Open-Plan Classrooms and Multi-Use Spaces

Every contemporary school wants to pride itself on a modern building. Oftentimes, that means open-plan classrooms, high ceilings, and large shared areas. These layouts support collaboration but create uncontrolled acoustic spillover:

  • In open-plan environments, noise from one teaching zone leaks into another.
  • Multipurpose halls double as dining areas, performance spaces, and sports facilities, making them acoustically complex and unpredictable.

Without tailored acoustic zoning or absorption, these spaces generate high background noise and unacceptable speech-to-noise ratios. These conditions are especially hard on pupils with hearing impairments, autism, or ADHD.

 

Illustration of a classroom with desks and chairs.

 

HVAC Noise and External Interference

Mechanical systems like ventilation, air conditioning, or heating units often produce low-frequency noise and vibration. While subtle, this continuous hum or rumble competes with the teacher’s voice. This is most evident in rooms where ceiling-mounted fans or vents sit directly above student seating.

Meanwhile, external noise from traffic, playgrounds, construction, or emergency vehicles can infiltrate classrooms through poorly sealed windows, thin walls, or uninsulated façades. These interruptions break student focus, raise stress levels, and interrupt classroom flow.

Ignoring how sound will behave in a situation like a school can almost nullify the effect of being there - students learn nothing, teachers get fatigued, and parents get frustrated by the lack of results. The price of treating acoustics as an afterthought is higher than the treatment itself. 

Lack of Zoning and Acoustic Separation

Inadequate acoustic zoning means classrooms bleed noise into corridors, adjacent rooms, or staff offices. Often, there’s no sound-rated door or partitional isolation between learning and non-learning spaces. 

This absence of separation not only affects learners but also staff: teachers struggle with vocal strain, and support workers find it harder to provide one-on-one assistance in acoustically chaotic environments.

It's inevitable - some classes are louder than others, and some teachers can't enforce obedience as well as others. This becomes a problem for everyone close, without acoustic treatment. It takes time to learn how to behave properly. That IS one of the reasons we go to school. And if schools don't support this process adequately, it would take even more time to learn and grow.

Measuring and Understanding the Acoustic Problem

Before solutions can be applied, the problem must be measured. In acoustics, what you can’t quantify, you can’t control. Schools often suffer from poor sound environments without even realising it. The key to meaningful change lies in understanding exactly how sound behaves in a space.

Why Reverberation Time Matters

Reverberation time, commonly referred to as RT60, is one of the most important metrics in classroom acoustics. It refers to how long it takes for a sound to decay by 60 decibels once the source has stopped.

Why 60 dB? It's the sound level at which we perceive the sound wave has stopped. In educational settings, longer reverberation times mean speech becomes smeared, harder to distinguish, and more exhausting to follow.

The recommended RT60 for classrooms is typically under 0.6 seconds, depending on room size and age group. Anything higher leads to sound reflections that compete with the teacher’s voice, especially detrimental in rooms with hard flooring, bare walls, and large windows.

Acoustic Audits: What They Actually Measure

An acoustic audit is a structured assessment that evaluates a room's suitability for its intended use. It's the first step in any project we take. In schools, it includes measurements like:

  • RT60 across octave bands (to identify where echoes are worst)
  • Ambient background noise levels, both internal (HVAC) and external (traffic, playground)
  • Sound insulation performance, often across classroom partitions or hallways

Audits also include site observations: Are students visibly distracted? Is the teacher raising their voice constantly? Is there an echo or feedback when using microphones?

These audits form the evidence base for targeted interventions, and prevent money being wasted on the wrong treatment. Being a key factor in the whole acoustic treatment, measurements are better done by professional acousticians.

Understanding the Speech Transmission Index (STI)

If RT60 tells us how long sound hangs in the air, STI tells us how clearly it is understood. The Speech Transmission Index is a scale from 0 (poor) to 1 (excellent) that evaluates how intelligible speech is in a given space.

In classroom settings, an STI of 0.75 or higher is considered desirable for effective communication. Below that, students begin to struggle with comprehension.

High STI values result from low background noise, controlled reverberation, and clear, direct sound paths from teacher to listener. In poorly treated environments, even the best teaching methods become less effective, simply because students can’t clearly hear what’s being said.

According to Cognitive Load Theory, the brain has limited working memory. If a large portion of that capacity is used just to interpret garbled speech, less is left for actual learning.

What starts as a “minor acoustic flaw” results in:

  • Faster mental fatigue
  • Reduced engagement
  • More repeated instructions
  • Lower retention and academic performance

And let’s not forget teachers, who must raise their voices constantly and deal with the added frustration of disengaged or confused students. Over time, this can lead to:

  • Vocal strain
  • Burnout
  • Higher absenteeism

Effective Acoustic Solutions for Schools

Acoustic upgrades in educational spaces don’t have to mean full-scale renovations. A mix of strategic materials, architectural tweaks, and smart product choices can drastically reduce reverberation time, improve speech intelligibility, and create a calmer, more focused environment for both learners and educators.

We are talking about schools, so we should act smart about renovations. 

Ceiling Treatments: The First Line of Defence

Ceilings are often the largest uninterrupted surfaces in a classroom, and one of the most effective areas to treat.

  • Acoustic ceiling tiles, especially Class A-rated mineral fibre or polyester-based panels, help absorb mid-to-high frequency sound, which includes most of the human voice range.
  • Suspended acoustic baffles, like our Echo Cloud, can be hung in large halls or high-ceilinged areas to break up standing waves and reduce echo. These are particularly useful in gyms, cafeterias, or open-plan learning zones.

These treatments reduce RT60 values, often halving reverberation time when installed correctly.

Wall-Mounted Absorbers and Corner Panels

While ceilings address vertical reflections, wall-mounted acoustic panels tackle lateral reverberation: the kind that makes speech smear and voices sound distant.

  • Panels like our DOMINO or ACER should ideally be placed at ear height around the perimeter of classrooms.
  • Bass traps or corner absorbers can be useful in music rooms or multi-use halls where low-frequency build-up causes muddiness and discomfort.

For best results, panels should have high NRC (Noise Reduction Coefficient) ratings and be distributed to break up parallel surfaces.

Doors, Windows, and Soft Finishes

Many school acoustic problems come not just from within a room but from adjacent spaces or outside.

  • Acoustically sealed doors. 
  • Door seals and drop-down acoustic seals reduce sound transmission between classrooms or corridors.
  • Double-glazed or laminated windows with acoustic interlayers help minimise external noise from roads or playgrounds.
  • Thick curtains, carpets, and upholstered furnishings add passive absorption and help limit flutter echoes.

While these aren't substitutes for proper acoustic insulation, they often improve the acoustic comfort in under-treated spaces.

Layout Tweaks and Zoning

Simple layout changes can often yield surprising improvements in sound management. Zoning helps reduce noise paths and limits the spread of ambient noise, which is crucial in shared-use environments.

  • Avoid placing noisy equipment (printers, projectors, HVAC vents) near high-use seating areas.
  • Use bookshelves, lockers, or partitions to create acoustic barriers in open spaces.
  • Where possible, schedule high-noise activities in areas that have already been acoustically treated, or at different times to minimise overlap.

Temporary vs. Permanent Options

Not every school can afford a full refurbishment, and funding cycles can be unpredictable. Fortunately, there are modular and cost-effective solutions for both the short and long term:

Temporary / Budget-Friendly:

  • Freestanding acoustic screens
  • Portable acoustic partitions
  • Clip-on wall panels and foam tiles
  • Curtain tracks with mobile drapes

Permanent / High-Performance:

  • Full-ceiling tile replacement
  • Integrated acoustic wall panels
  • Floating flooring systems for music rooms
  • Purpose-built acoustic louvres or HVAC duct silencers

Transforming Multi-Use and Shared Spaces

Modern schools are built for versatility. They aim to provide comfort and valuable education to a broad spectrum of students. That often comes at the cost of acoustic control.

Large, shared spaces like canteens, gyms, libraries, and auditoriums each present unique acoustic challenges. And when untreated, they quickly become chaotic, overwhelming environments that compromise both well-being and performance.

One Size Doesn’t Fit All: The Problem with Uniform Design

Without tailored acoustic treatment, these multi-purpose environments become echo chambers that spike noise levels beyond acceptable thresholds, often exceeding 85 dB during peak use.

More than enough to trigger discomfort, stress responses, and even hearing risks over time. Reverberation is amplified by:

  • Hard, reflective surfaces (tile floors, concrete walls, glass facades)
  • High ceilings with no diffusive treatment
  • Irregular usage: lunch rush, PE sessions, school assemblies; all with radically different sound pressure levels.

The different types of noise (airborne, impact, vibration, echo, reverb, etc) are counteracted with acoustic treatment, specifically designed for them. If one space has many uses, that creates an opportunity for it to be a habitat for different activities, therefore different types of noise. This complex sonic nature needs to be understood and planned for when the time for acoustic treatment comes. 

Adaptive Acoustic Solutions: Designed for Flexibility

The key is solutions that respond to a space’s changing use.

  • Suspended baffles or acoustic clouds: Effective in gyms and dining halls where open volume amplifies footfall and speech. These can be arranged to maintain airflow while dramatically reducing reverberation.
  • Modular wall panels: In libraries or lecture theatres, magnetic or hook-and-loop panels allow schools to scale absorption up or down as needed.
  • Acoustic curtains: Especially useful in auditoriums or stage areas, where soft treatments can be drawn during performances or teaching sessions and retracted for cleaning or maintenance.

Each of these options can be selected based on NRC (Noise Reduction Coefficient) ratings and fire safety compliance, ensuring performance without compromising regulations.

Crowd Noise and the Psychology of Transitions

Sound interferes with learning. That much is clear. But it also affects how students feel in the in-between spaces. Canteens, hallways, and locker areas are acoustic bottlenecks, where voices bounce and compound.

The result? Elevated cortisol levels, reduced focus in the following class, and strained communication between students and staff. A relentless cacaphony of noise, voices and whatnot. 

Strategically placed absorption zones (think: ceiling tiles above queue lines or panels around seating clusters) can drop background levels by 5–10 dB, enough to:

  • Reduce the sensation of crowding
  • Improve speech clarity
  • Calm the transition experience between classes

In libraries, high STI (Speech Transmission Index) values are vital to preserve speech privacy and maintain a quiet, focused atmosphere. Acoustic zoning with bookshelves, rugs, or vertical panels can segment the space without architectural walls.

Building Better Schools Through Sound

Acoustic design isn’t an afterthought or a “nice-to-have” feature once the furniture is in. It’s a foundational element of effective education. Just like air quality, daylight, or temperature, sound shapes how we think, feel, and learn.

When schools invest in their acoustic environments, they reclaim clarity, calm, and connection. They support both the cognitive performance of students and the well-being of staff. They build classrooms where every word matters, every voice is heard, and no child is left behind because of a muddy echo or a booming hallway.

The science is clear, and the tools exist. What’s needed now is the will to design for better outcomes from the start, or retrofit where it matters most. Great learning needs great environments.

Is your space haunted by annoying echoes, distracting noise, or unclear sounds? We've been there too. Acoustic problems in any space can disrupt your plans and peace of mind. 

Think of sound as a naughty kid at your party - sometimes it is too loud, sometimes it is too timid and doesn't want to interact with the others, and it never quite behaves as it should. That’s where acoustic panels come in, but even they aren’t without their quirks. 

Use this guide to understand the common issues with your acoustic panels and, more importantly, to understand how to solve them. From poor placement to aesthetic conflicts, we’ll walk you through each problem and offer practical, expert-approved solutions to help you reclaim control of your space’s acoustics.

 

Common Acoustic Issues in Residential Buildings

Poor acoustics in a room can result from several factors, including the room's shape, construction materials, and furnishings. Common acoustic defects such as echo, reverberation, and sound leakage occur when sound waves reflect off hard surfaces or escape through gaps and cracks. For instance, rectangular rooms with hard surfaces like glass or concrete tend to create excessive echo, while rooms with uneven surfaces can lead to sound distortion.

Architectural design, construction materials, and the layout of a building significantly impact its acoustics. Buildings with high ceilings, hard floors, and large glass windows often suffer from excessive reverberation, while those with thin walls may experience significant sound leakage between rooms. These issues can compromise privacy, productivity, and comfort in both residential and commercial settings.

Acoustic Panel Limitations and Challenges

While acoustic panels are highly effective at absorbing sound, they are not without limitations. Here is what to have in mind before installing your acoustic panels so that the result won't disappoint you:

  • Frequency Absorption: Not every panel will solve every acoustic need of yours. Not all panels are equally effective across the full range of sound frequencies. Some are better at absorbing high frequencies (like speech), while others are more suited to low frequencies (like bass sounds). Therefore, it's crucial to define precisely the purpose of the acoustic treatment you desire, and next, to properly combine different types of acoustic panels. And yes, we can help you with that!
  • Aesthetics: Acoustic panels can sometimes clash with the existing decor, especially if their design does not match the room’s aesthetic. Luckily, we have a variety of options, including colours and materials, so that you can find the right interior design combination.
  • Maintenance: Over time, acoustic panels can accumulate dust and dirt, which may affect their performance and appearance. Regular cleaning and maintenance are required to keep them in top condition. Good news - all of our acoustic panels are low-maintenance and easy to clean.

How Long Do Acoustic Panels Last?

The lifespan of acoustic panels largely depends on the material, quality, and installation environment. High-quality panels can last for decades if properly maintained, while cheaper options may degrade faster. Environmental factors such as humidity, temperature changes, and exposure to direct sunlight can also affect the durability of acoustic panels. Make sure to use relevant acoustic panels for the different spaces.

One good example is the usage of our wood wool acoustic panels in SPA centres and indoor pools. These panels thrive in humid environments while eliminating the well-known annoying echo of such places.

Should I Cover All Walls with Acoustic Panels?

Not necessarily. The key to effective acoustic treatment is strategic placement rather than total coverage. For example, focusing on the first reflection points - areas where sound waves first hit walls - can significantly reduce echo and reverberation without needing to cover every surface. Over-treatment with panels can lead to an overly dampened room, which might make it feel lifeless or dull.

Common Problems with Acoustic Panels

Problem #1: Uneven Sound Distribution

Possible Reason: Incorrect Placement of Panels

Improper positioning of acoustic panels is a common issue that can render them ineffective. Placing panels too high on the walls or in areas where sound does not reflect can reduce their ability to absorb sound effectively.

It’s essential to identify primary reflection points and areas with the most noise impact to ensure maximum efficiency.

Solution: Position panels at ear level on the walls, where sound reflections are most prominent. In-home theatres or studios, ceiling hanging baffles should be placed above mixing or listening areas to capture sound waves effectively.

Aim for at least 30% coverage density of the total ceiling area.

 

Problem #2: Minimal Improvement in Acoustics

Possible Reason: Insufficient Coverage

Insufficient coverage occurs when the acoustic treatment does not cover enough of the room’s surfaces to significantly reduce sound reflections and reverberations.

Acoustic panels are effective only when they are strategically placed in sufficient quantities. If too few panels are used or they are only placed in one area, the overall impact on sound quality is minimal.

In large or high-noise environments, inadequate coverage will fail to address the acoustic issues, leaving parts of the room untreated and maintaining problematic echoes and sound reflections.

Solution: If there are too few panels or they are too small, they won’t absorb enough sound waves, leading to limited acoustic improvement. To achieve better sound control, aim to cover at least 15-30% of the total wall surface area, depending on the room's size and use.

Larger or noisier rooms may require greater coverage. Assess the specific acoustic needs of your space and adjust panel placement and coverage accordingly for optimal results.

Problem #3: Inconsistent Sound Absorption

Possible Reason: Material Incompatibility

Different acoustic panel materials have unique sound absorption characteristics, which means that using the wrong material can lead to ineffective sound treatment.

Foam panels are excellent for high-frequency noise but may not perform well in absorbing low frequencies. When materials are chosen without considering the room's acoustics and the type of sound issues present, the result is often inconsistent sound absorption.

Solution: Different materials have varying sound absorption properties. Choosing the wrong material for your acoustic panels can lead to inconsistent sound absorption.

Select materials that match the acoustical needs of your environment. Fabric-wrapped panels are ideal for office spaces due to their balance of absorption and aesthetics, while foam panels may be more suited for a home studio.

Always consider the specific use and desired acoustics of your space when selecting panel materials.

Problem #4: Reduced Acoustic Performance

Possible Reason: Poor Maintenance

Over time, acoustic panels can accumulate dust, dirt, and even mould in humid environments, which can degrade their performance and appearance.

Solution: Regularly clean panels using a vacuum with a brush attachment or a damp cloth for fabric panels. In environments prone to high humidity, consider using moisture-resistant panels or adding a dehumidifier to the room.

Luckily, all of our acoustic panels are extremely easy to maintain and are ready to serve you for decades.

 

How-to-fix-common-problems-with-acoustic-panels-maintenance

 

Problem #5: Overly Damped Sound

Possible Reason: Overuse of Panels

Overusing acoustic panels can lead to an overly dampened environment, resulting in a space that sounds flat and lifeless. This problem occurs when too many panels are installed without consideration of the room's natural acoustics, absorbing not only unwanted noise but also desirable sound qualities.

Such excessive dampening can strip the room of its natural resonance, making it uncomfortable or unnatural for its intended use, whether it’s for music, conversation, or relaxation.

Solution: Using too many acoustic panels can overly dampen a room, making it sound lifeless. To avoid this, use only the amount of treatment necessary to achieve your desired sound quality.

A balanced approach is key - conduct sound tests and experiment with different configurations to find the perfect balance that enhances the acoustics without over-damping.

 

Problem #6: Panels Detaching from Walls or Ceilings

Possible Reason: Improper Installation

Incorrect installation can compromise the effectiveness of acoustic panels. Panels that are not securely mounted can fall, causing damage and reducing their sound absorption capabilities.

Using inadequate adhesive or mounting hardware is a common reason for acoustic panels detaching from surfaces. This can occur due to the weight of the panels or the type of surface they are being mounted on. If the adhesive or hardware isn't rated to hold the panel securely over time, panels may fall, reducing their effectiveness and potentially causing damage.

Different surfaces, such as painted drywall, concrete, or wooden walls, require specific mounting solutions to ensure that panels stay in place and function properly.

Solution: Acoustic panels that are not mounted with the appropriate adhesive or hardware can detach from surfaces, reducing their effectiveness and posing a safety risk.

Use high-quality, manufacturer-recommended mounting materials and the provided installation guides to ensure panels stay securely in place. For heavy panels or installations on ceilings, additional supports or brackets may be necessary to maintain stability and sound absorption performance.

If you are not feeling like a DIY enthusiast today, you can always contact our professionals to install your panels, especially in complex spaces or large installations.

Problem #7: Limited Sound Absorption Range

Possible Reason: Lack of Panel Variety

When only one type of acoustic panel is used, the sound absorption is often limited to a narrow range of frequencies. Different materials and panel designs are required to absorb low, mid, and high frequencies effectively.

A lack of variety in panel selection can result in certain frequencies not being absorbed, leaving some sound issues unresolved. This limitation can affect the overall sound quality in a space, failing to provide a comprehensive acoustic result.

Solution: Using only one type of panel can limit the range of frequencies absorbed, leading to poor overall sound quality. To improve sound absorption across a broader frequency range, combine different types of acoustic panels.

Use a mix of bass traps, diffusers, and mid to high-frequency absorbers to address the full spectrum of sound. This combination ensures comprehensive acoustic treatment, enhancing the sound experience in the room.

Additional Problems to Watch For

Beyond the most common issues, there are a few less obvious problems with acoustic panels that can still have a noticeable impact on performance and aesthetics. Being aware of them helps you maintain both the function and the look of your installation:

  • Fading or discolouration over time – Especially in rooms with direct sunlight, fabric-covered panels can lose their colour vibrancy. This doesn’t just affect aesthetics – UV exposure can also slightly alter the fabric’s acoustic permeability.
  • Fabric wear or fraying – In high-traffic areas or spaces where panels are frequently touched, fabrics may start to fray, snag, or develop a worn look. This can shorten the panel’s usable lifespan.
  • Moisture damage – In humid environments, such as basements or coastal locations, panels can absorb moisture, leading to warping, mould growth, or a change in acoustic performance. For such areas, select panels specifically created for a humid environment, for example, wood wool acoustic panels.
  • Damage during cleaning – Using harsh chemicals, abrasive tools, or excess water can degrade panel fabrics or alter the surface texture, affecting both absorption and visual appeal.
  • Attracting dust and allergens – Some fabric textures tend to gather dust, pollen, and airborne particles. Over time, this build-up can dull the surface and impact air quality if not cleaned properly.

 

Improving Room Acoustics in Specific Settings

To effectively address acoustic issues, it’s crucial to diagnose the problem correctly and apply the right solution. For example, if a room suffers from excessive echo, adding more panels or using panels designed to absorb specific frequencies can help.

Start with a sound analysis to identify the room's problematic areas. Adjust the number and placement of panels based on this analysis. In many cases, adding bass traps in corners can significantly improve low-frequency absorption, while wall panels can manage mid to high frequencies.

Don't forget that different environments have unique acoustic needs. For example:

  • Home theatres: Require a balanced mix of sound absorption and diffusion to create an immersive sound experience without deadening the room.
  • Offices: Need to reduce background noise to enhance concentration and privacy, typically using ceiling baffles and wall panels.
  • Restaurants: Must manage background noise to create a pleasant dining experience, often employing a combination of ceiling and wall panels.

 

What Makes a Good Acoustic Panel?

A good acoustic panel effectively absorbs sound across a broad range of frequencies and is durable, aesthetically pleasing, and easy to install. Key characteristics to consider include:

  • Material: High-density materials such as wood or wool are excellent at absorbing sound.
  • Thickness: Thicker panels generally provide better sound absorption, especially at lower frequencies.
  • Design: Panels should complement the room's aesthetic, with options ranging from fabric-covered to perforated wood designs.

 

How-to-fix-common-problems-with-acoustic-panels-design-interior

 

Good acoustics result from a combination of effective sound insulation, absorption, and diffusion. Buildings with good acoustics typically have well-designed room layouts, appropriate use of materials, and strategic placement of acoustic elements.

While acoustic panels are effective for improving room acoustics, it's important to start with soundproofing of walls, floors, or ceilings to significantly reduce airborne and impact noise.
