See: Resistive Absorbers, Diaphragmatic Absorbers, Resonant Absorbers, Absorption Coefficient, Sabine. Absorption Coefficient The proportion of incident sound that is absorbed by a surface. Usually this is expressed as a number between 0 and 1, or a percentage. In most materials, the amount af absorption changes with the angle of incidence.
