Wall Soundproofing Solution 3
An independent stud wall.- The most effective form of soundproofing walls
When soundproofing a wall it is necessary to improve three basic components.
1) The mass of the wall- This is normally achieved by adding acoustic plasterboard.
2) The Resilience of the wall- This is the springiness of the wall. Without this, the addition of the mass will have very little impact.
3) The sound "absorbancy" of the wall. By adding different components the sound gets trapped more easily within the wall- The most cost effective method is the use of acoustic mineral wool.
However where noise is extreme from next door we have to add further elements
4) Width of soundproofing-the wider your soundproofing barrier the better it performs. Hence 100mm wall are better than 50mm
5) Separation - The wider the soundproofing solution the more effective. However a physically separate wall ( even if separated by 10mm from the original wall provides a significant uplift in performance.
6) Acoustic Barrier- For the absolute maximum protection an acoustic membrane can be incorporated into the mix.
Where the level of noise from the neighbouring wall is extreme, the erection
of an independent stud incorporating acoustic materials will provide the greatest
level of wall soundproofing.
The Stud can be constructed from either wood or metal. We provide a series calculators designed to help you work out what you need for different sized walls. Obviously if space is at a premium then construct a 50mm stud wall with a minimal gap ( 10mm) between it and the offending wall. The stud work should not touch the offending wall at any point,
and should be affixed to adjacent walls floor and ceiling.
The stud work should
be in-filled with the appropriate thickness of acoustic mineral wool, i.e. 75mm
in this case. The construction on the stud wall follows the same pattern as
the the other wall solutions ideally incorporating resilient bars (like Solution
2 ) and certainly a double
plasterboard layer. With this construction the filling of floor and ceiling
voids with acoustic mineral wool (AMW60 100mm) immediately adjacent to the offending
wall needs to be considered as this will typically be the weakest acoustic link
post construction. In order to keep the wool in place it might be necessary
to staple chicken wire or similar meshing to the rear of the stud work. Be aware of the possibility of flanking sound issues in breeze block party walls.
