Shock-mounted Wall Soundproofing Structures

Soundproofing of a given wall with inadequate sound barrier rating can be attained in two ways:

• 1 – Adding sheer mass to the existing structure by correctly building another wall in front of the first with a suitably calculated air-gap, which can (in the best case scenario) never be smaller than 50mm for technical reasons. This is not always possible on floors above the ground floor due to architectural issues and also demands availability of appreciable (lost) space as regards length and width of the room, which is usually in the region of about 21.5 cm of extra forward protrusion per wall.

• 2 – Assembly of a shock-mounted soundproofing structure where the frame is “floating” on shock-mounts (not in contact with the wall, floor or ceiling), and allows the outer further spring-loaded visible surface to vibrate and absorb sound by converting audible energy into kinetic energy (motion) and heat. This requires less than half the required wall protrusion dictated by the first method.

In certain areas requiring high performance (pertaining mostly to loud music), both of these treatments may be required at the same time, and hence the need to plan these particular spaces to be situated at the bottom-most level of the building in question.

Our soundproofing wall structures can be assembled to attain barrier ratings which surpass 60 dB Rw on flat surfaces.

By taking on-site room and noise measurements and running a computer simulation, we can propose a suitable soundproof partition structure required for the particular walls and also tune the spacing between spring-mounts to complement performance in terms of acoustic response of the room.

Available options:

  • Ultra-thin 19mm wall coverings for human voice, animals and birds.

 

  • Shock-mounted wall soundproofing for sub-woofers and other low frequencies – up to 78 dB Rw (66 dB @ 100 Hz)
