Soundproofing is the act of stopping sound from entering or leaving a space; stopping sound being transferred from one area to another.
This is achieved through different methods depending on the location. We will look at the different stages of where and when soundproofing can be implemented and how its effectiveness will be altered by different factors.
Building stage soundproofing
Ideally, soundproofing will be a consideration at the build stage of buildings and rooms and be incorporated to suit the intended us of the space. In these circumstances, the use of mineral wool inside wall cavities, creation of air gaps using Isomax clips and channels, using underscreed acoustic flooring and perimeter/isolation strips around the edge of the room and under partition walls all are excellent methods of reducing/eliminating sound transference.
In addition to these methods, the use of sound blocking ceilings is also an excellent method. The installation of a suspended ceiling grid with soundproof tiles, sound blocker panels above them and a product such as Ecophon extra bass placed above the ceiling will help to stop sound transferring between partitions.
Room repurposing soundproofing
Changing the use of a room presents problems for example when converting a normal room into a recording studio, broadcast room or similar.
In these cases, stopping outside sound coming into the room is a priority. Not wanting to break into partitioning walls, the creation of false wall is possible using products like Acoustiwall which is placed on top of existing walls and sealed with an acoustic sealant. The Acoustiwall comes decorating ready and is an excellent start.
On top of this, the use of putty pads inside plug sockets, acoustic carpet underlay (such as soundlay) adds extra soundproofing function. In these circumstances it is good practise to lift the skirting and run the acoustic underlay up the wall slightly, reattaching the skirting on top of the underlay, creating an acoustic barrier.
Acoustic suspended ceilings can also be installed at this stage, but where this is not possible, there are a few options to stop transmission through a solid ceiling. Though not as effective as they would be if done in the build stage, they are highly effective at stopping sound transmission to an acceptable level where the noise above is normal foot fall etc:
- The use of isomax clips and channels attached either directly to the ceiling or a timber frame and the attaching of acoustic and soundproofing plasterboard
- Application of TecSound directly onto the soffit, covered with an acoustic fabric such as BuzziSkin or Autex Composition. The TecSound will block sound, while the acoustic fabric/wallpaper will help internal acoustics and provide an aesthetically pleasing finish to the ceiling
- Where possible, the installation of acoustic underlay on the floor above the room would also be desirable in addition to the above. This will reduce footfall noise and, depending on the product chosen, some airborne sound.
