Reverberation Chambers reflect sounds to produce a non-directional or diffuse sound field within the chamber. Reverberation chambers are also used to measure the sound absorption characteristics of materials or other items such as soft panels, screens or pieces of furniture (e.g. theatre seats, chairs, and sofas)
ETS-Lindgren reverberation chambers provide a diffuse-field environment that enables sound absorption tests, sound power tests, and transmission loss studies to be performed.
