QuietStone is a noise reduction tile system developed by Sound Absorption UK Ltd which combines significant acoustic absorption capabilities with long life and aesthetic effects. The tile is specifically designed with air cavities which absorb unwanted frequencies of sound to create a more comfortable environment. The tiles or blocks are made of bonded natural material which creates the required air cavities which in turn produces advanced sound reduction properties.
QuietStone is a rigid, hard wearing, easily cleaned cladding material with the appearance and texture of pumice stone. Yet it offers sound absorbing properties better than many soft materials and, correctly installed, sound insulation equivalent to a solid brick wall.
Correctly installed QuietStone will not only give you the optimum acoustic balance within the studio but will also protect your recording from unwanted external noise. And of course sound penetrating out of the studio is dramatically reduced allowing the rest of your staff to work unhindered.
QuietStone has other advantages such as a two-hour fire rating and complete cleanability. QuietStone can be vacuumed, scrubbed and washed with detergents or even bacteriocides without damage. Like any other normal wall it will take fixings for shelves, speakers, lights etc. QuietStone can be cut to shape around such things as light switches, sockets and other electrical fittings. Cabling can be hidden behind QuietStone and individual panels can be made detachable for easy access to fuse boxes and other electrical installations.
