How to Soundproof a Stud Wall

How to Soundproof a Stud Wall

Stud Wall Soundproofing

This guide will show you the best method to soundproof a stud wall. These soundproofing techniques and materials are used to soundproof existing and new stud walls.

How does sound transfer through a stud wall?

Sound is a wave of energy that travels through the air. Once it comes into contact with an object like a stud wall, it will vibrate through an untreated wall to the other side. Airborne sounds, such as conversation, vibrate through solid structures. Once they are through to the other side, the sound becomes audible. A soundproof stud wall will stop the sound transfer between the rooms if you use the following soundproofing techniques.

Soundproofing techniques for stud walls

Add mass/density – By increasing the mass of your stud wall, you will block the transfer of noise between rooms. Using acoustic insulation and soundproof plasterboards will add mass and density to your stud wall.

Decoupling/isolation – Sounds transfer through the structure of the stud frame as vibration. The best way to stop the vibration is to use sound isolation clips on the frame. The Acousticlip is the best performing sound isolation clip for stud walls.

Sound absorption – Improve the ability of the wall to absorb sounds using sound insulation slabs and acoustic membranes.

Soundproofing materials for stud walls

Use these soundproofing materials to soundproof a new or existing stud wall to stop airborne and vibration noise.

Insulation for stud wall soundproofing

DFM acoustic insulation slabs are an essential soundproofing material to increase the airborne sound insulation performance of walls, floors and ceilings. Because of its mass, density and sound absorption properties, acoustic insulation is used in soundproof systems inside ceiling cavities, stud walls and floor joists. Available in various thicknesses and densities, we recommend using the 60kg slabs for their acoustic performance.

AcoustiClip – Sound Isolation Clip

The AcoustiClip reduces vibration sounds through walls and ceilings. AcoustiClip is a high performing sound isolation clip used to decouple walls and ceilings. Use this decoupling clip as part of your separating wall or ceiling solution for superior levels of noise control. The AcoustiClip is featured in most of our wall and ceiling soundproofing systems as it reduces vibration and impact sound by isolating walls and ceilings. Combine the AcoustiClip with acoustic insulation and soundproof plasterboards, and you will ensure the best levels of noise control.

Noisestop 1 Plus Panel

Noisestop 1 Plus Panel is a high-mass, dense acoustic soundproof panel that will insulate ceilings and walls acoustically. It is designed to block the transmission of sound effectively. Noisestop 1+ Panel is instrumental in creating robust ceilings and wall linings. A premium, slim, high-mass acoustic board suitable for ceilings and walls. Outperforming standard ‘soundproof’ plasterboards, its versatility in installation makes it an ideal standout choice. This versatile panel combines mass and sound absorption in all our soundproofing wall and ceiling systems. Comprising a 10kg mass loaded vinyl membrane pre-bonded to a 12.5mm acoustic plasterboard eliminates the need for separate soundproof membranes. It significantly bolsters the sound insulation performance of walls and ceilings within soundproof systems.

Soundproof Plasterboard 15mm

Reduce noise transmission in your home with this high-density Acoustic Plasterboard 15mm. This acoustic plasterboard makes a fantastic soundproofing alternative for your home or workspace with a greater density than standard plasterboard. Once installed, you’ll notice a reduction in noise transmission through your walls and ceilings, especially when combined with other soundproofing solutions.

Isolation Strips

Isolate stud wall frames from the building’s structure or over floor joists to isolate the floorboards. Isolation Strips decouple surfaces, reducing sound transfer by absorbing vibration. They are supplied in 10-metre rolls with a self-adhesive (s/a) back. Noisestop isolation strips are quick and easy to install. Available in three widths: 50mm, 75mm and 100mm. Just choose the isolation strip that suits your wall or joist width. The self-adhesive backing will bond to the most common substrates.

Acoustic Sealant

AC50 acoustic sealant is a high-strength, permanently flexible acoustic sealant and adhesive. Acoustic sealants are specially formulated to seal the edges and around the perimeter of plasterboard walls and ceilings. One standard sealant tube will be enough to seal approximately five soundproofing panels at 1200mm x 1200mm. It’s available to buy in a standard 380ml or large 900ml size (you will require the large applicators to dispense the 900ml tubes).

Silent Panel

Noisestop Silent Panel, the highest performing direct wall soundproof solution, effectively block unwanted neighbour noise without sacrificing valuable living space. This 30mm thick soundproofing wall panel directly reduces noise transmission through walls, significantly reducing up to 52dB in audible airborne sounds. Specifically designed for timber stud, brick, and concrete block walls, the Noisestop Silent Panel is the top choice in our direct-to-wall soundproofing range, effectively combating clearly audible conversations and TV noise. Directly fixing to existing walls makes installation hassle free, ensuring minimal disruption for homeowners.

Stud wall soundproofing solutions

Stud walls are the most common construction method in homes to separate rooms, and these stud wall solutions will effectively block high noise levels. Stud walls can also be used to insulate party walls against noisy neighbours or to create a room within a room when a high level of noise control is required for studios and home cinemas.

Noisestop Systems provides a range of DIY stud wall soundproofing systems that combine all the necessary acoustic products.

Stud wall soundproofing conclusion

Soundproofing stud walls can greatly enhance the peace and privacy within a space. By implementing effective techniques such as using soundproofing materials, insulation, and proper construction methods, it’s possible to reduce the transmission of sound between rooms significantly. Whether for a home, office, or any other environment, soundproofing stud walls can make a notable difference in creating a more peaceful and comfortable atmosphere.
