Sound Absorbing Ceiling Tiles

Sound Absorption is one of the primary acoustic functions of ceiling tiles. Sound is reflected off surfaces back into the room much like light, softer materials will absorb some of this energy, which will help prevent an echoey environment and maintain sound clarity.

Each tile has a rating measured in alpha waves between 0.0 (no sound absorption) and 1.0 (100% sound absorption), but for ease of comparison, manufacturers tend to categorise tiles into classes ranging from ‘A’ (best sound absorbers) to ‘E’ (poorest sound absorbers). Generally speaking, for good sound absorption you will want a tile rated Class C or above, this is also the minimum requirement for new suspended ceilings in schools. Below are a range of suitable tiles with ratings.
