Is your space haunted by annoying echoes, distracting noise, or unclear sounds? We've been there too. Whether you’re trying to create the ideal home theatre, a creative office environment, or a peaceful living space, acoustic problems can disrupt your plans and peace of mind.
Think of sound as a rebellious guest at your party - sometimes it’s too loud, sometimes it’s too quiet, and it never quite behaves as it should. That’s where acoustic panels come in, but even they aren’t without their quirks.
This article is your ultimate guide to understanding the common issues with acoustic panels and, more importantly, 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 Dampened 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-dampening.
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.

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.
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 Theaters: 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 first with soundproofing of walls, floors, or ceilings to significantly reduce airborne and impact noise.
