Noise has a way of creeping into your life when you least want it.

A neighbour’s TV that feels louder at night. Office chatter that never truly ends. Even in beautiful homes, sound finds every weakness: through the wall, around the edges, and into the places where you should feel calm.

If you want to reclaim your space without rebuilding your entire room, MUTE SYSTEM™ - WALL SOUND INSULATION, developed by DECIBEL, is designed precisely for that purpose.

This is a point-connected wall soundproofing system, built around specially engineered MUTE panels and mounted with anti-vibration DClox™ fastening elements. Together, they create a highly effective barrier against unwanted airborne noise, while keeping the installation practical and straightforward.

It is suitable for a wide range of environments, including homes, offices, studios, restaurants, bars, and home cinemas.

Why soundproofing a wall changes everything

Soundproofing is not only about “less noise”. It changes the way a room feels.

A quieter room becomes a place where you can focus, rest, speak without raising your voice, and actually enjoy silence as something you own, not something you chase.

When you improve a wall’s sound insulation, you also improve the comfort of the whole space. The atmosphere becomes calmer. Conversations feel cleaner. Music feels more controlled. And that persistent irritation caused by background noise simply… stops.

What makes MUTE SYSTEM™ different?

MUTE SYSTEM™ is engineered to reduce sound transfer in a smarter way, using a combination of panels and vibration control.

Here is what that means in practical terms:

MUTE panels come in different thickness options: 23 mm, 33 mm, or 63 mm
The system is designed to reduce the contact area between the panels and the existing wall to below 1%
It is tested and certified with a weighted airborne sound reduction index
The panels are installed using anti-vibration DClox™ fasteners, helping to limit the transfer of vibration through the structure

In short, it is made to tackle noise at its most annoying points and prevent it from travelling further.

How to install MUTE SYSTEM™ - WALL SOUND INSULATION

Below is a step-by-step guide to installing MUTE SYSTEM™ using the official approach and recommended accessories.

Step 1: Assess the wall and define what you need

Before you install anything, take a moment to understand your wall and your noise problem.

Ask yourself:

Where is the noise coming from: neighbours, machines, or a shared space?
When is it worst: daytime, evenings, or all the time?
Is your priority comfort and calm, or higher acoustic control (for example, studio use)?

This helps you determine the required sound reduction level and select the best thickness option for your project.

Step 2: Measure your wall and order the right quantity

Measure the height and width of the wall (or walls) you want to soundproof.

Using those measurements, calculate how many MUTE panels you need, then choose your preferred thickness:

23 mm
33 mm
63 mm

The thickness should match the level of sound reduction you are aiming for.

Step 3: Prepare the area properly

A clean installation is a better installation.

Before you start:

Remove furniture or items close to the wall
Clear wall décor and fittings where needed
Ensure the area is clean and free of dust and debris

Even small obstacles can slow down the process and affect alignment.

Step 4: Tools and accessories you will need

For installation, gather:

Tape measure
Drill with bits
Screwdriver
Spirit level
Gloves
Safety goggles

You can also choose additional DECIBEL accessories from the shop to further enhance performance.

Step 5: Install MUTE SYSTEM™ (core installation)

Follow these steps carefully for the best results:

☑️ Attach the anti-vibration DClox™ fasteners to the wall surface at regular intervals, as recommended by DECIBEL. Ensure they are fixed securely and evenly across the wall.

☑️ Apply sound and vibration-insulating sealant around the edge of each MUTE panel before installation. This helps reduce sound transmission further, especially at the perimeter.

☑️ Place the MUTE panels onto the DClox™ fasteners, ensuring secure attachment and proper alignment. Use a level so everything stays straight.

☑️ Fix the panels using the provided screws, following DECIBEL’s instructions. Do not overtighten, as excessive pressure may affect soundproofing performance.

☑️ Repeat until the full wall is covered, forming a complete soundproofing layer.

Step 6: Upgrade performance with optional accessories

If you want to push your wall soundproofing further, DECIBEL offers additional accessories that can enhance the system’s performance.

Add a membrane for extra sound reduction

☑️ Install the membrane between the existing wall and the MUTE panels.
This adds 3 dB of sound reduction.

Use Sound and Vibro Isolating DCstrip Tape

☑️ Apply DCstrip Tape around the edge of each MUTE panel.
This adds 2 dB of sound reduction.

These additions are ideal when you want greater control and stronger results, especially in spaces where noise sensitivity is high.

Step 7: Get expert guidance when the project is specific

Every wall has its own story.

Different buildings, different constructions, different sources of noise. If you have unusual requirements, building constraints, or simply want to make sure you are choosing the right setup, it is always worth speaking to an expert.

DECIBEL offers personalised consultations to help you get the best result for your specific space.

Common mistakes to avoid (and how to get the best result)

Even the best soundproofing system performs best when installed with care. Here are a few practical mistakes to avoid:

Skipping the assessment step and choosing thickness without considering the noise source
Uneven alignment, which can affect the finish and fit
Overtightening screws, which may reduce performance
Ignoring the perimeter, where sound often slips through gaps

A clean, precise installation creates a cleaner, quieter result.
