The perforations within the metal tile allow the product to have a far greater sound absorption rating, therefore ensuring it can be used in a far wider choice of environments.
The perforated tiles are often supplied with either a fleece (very thin piece of fabric) or an acoustic pad (around 20mm deep, more dense). The sound travels up into the tile and is then either absorbed by the fleece, or rebounded by the pad, depending on the performance required for the room.
Various different perforation patterns available from the leading manufacturers including; Burgess, SAS and Armstrong.
