Sound Absorption

Sound absorption is the measure of the amount of energy removed from the sound wave as the wave passes through a given thickness of material. Fig. 3.31 is a schematic representation of sound absorption and reflection of an insulating wall. While propagating from air into an absorbing material, the sound wave could experience reflection or absorption thereby losing energy, experiencing ...
