There are numerous solutions to the problem of sound reverberation. Often a combination of several tools is implemented and can include rafts, wall panels, carpets and even free standing structures, although research has shown that ceilings have the biggest impact on the acoustic quality of open plan offices.
Ceiling tiles vary greatly in composition and pattern and by extension their acoustic performances are diverse. Many common tiles also have pinhole perforations on their face, which increase a tiles ability to absorb sound.
Each tile has a rating to demonstrate how good a sound absorber it is, measured in alpha waves: this rating is between 0.0 (no sound absorption) and 1.0 (100% sound absorption) but for ease of comparison, manufacturers tend to categorise tiles into 5 classes. These classes are denoted by letters – ranging from ‘A’ (best sound absorbers) to ‘E’ (poorest sound absorbers).
