Editor Staff answered 2 months ago

The purpose of sound absorption is to reduce or control the propagation of sounds within a room. It therefore helps to:
limit sound reverberation
reduce echoes
reduce the level of the sound wave
improve intelligibility of speech in a room
The sound absorption of materials is described by an absorption coefficient (αw).
The closer the αw is to 1, the more absorbent the material. The closer the αw is to 0, the less absorbent the material, meaning that the sound is totally reflected. Therefore, a material with an absorption coefficient of αw=0.8 absorbs 80% of incoming sound.
