Guide to soundproofing walls – How to soundproof a wall against noisy neighbours and other unwanted domestic sounds

You can separate wall soundproofing solutions into two categories, direct to wall solutions and soundproofing systems.

Direct to wall solutions are thinner and space-saving compared with soundproofing systems. They are suitable for stopping sounds at the lower end of the scale. Direct to wall solutions will stop airborne sounds such as background TV or muffled conversation. These solutions will not block vibration through your walls.
Soundproofing systems are a more robust method of soundproofing. Combining acoustic materials to form a soundproof wall will reduce high levels of airborne sounds and reduce vibration through the walls. Soundproofing systems will stop higher levels of sound, such as clear conversation and loud music.

Use acoustic insulation between stud frames to block and absorb sounds that typically transfer through this area. We recommend that DFM acoustic insulation slabs be used inside any cavity when soundproofing stud walls or solid brick walls.
Increase isolation of your walls using AcoustiClip. The design of the clip ensures noise that would typically transfer through the building’s structure can’t due to the separation created by the AcoustiClip. Vibration and airborne sounds reduce by using acoustic clips.
Soundproofing boards will increase a wall’s mass, enabling the wall to block more airborne sounds. The Noisestop Silent Panel is our best performing stand-alone board that can be applied directly over the existing walls to reduce airborne sounds. Most of our wall soundproofing systems utilise the Noisestop 1+ Panel. At only 18mm, it is one of the thinnest boards on the market but is excellent for combining with other materials to form an acoustic wall.
Seal the edges of the soundproof boarding and the perimeter of your wall with an acoustic sealant. Creating an airtight seal helps to ensure sound does not transfer through small gaps between the panels.
When you reinstate electrical outlets, use acoustic putty pads inside recessed back boxes to ensure the acoustic integrity of the soundproof wall.
