Sound absorption coefficient α
Detailed Description:
The sound absorption coefficient α of a material indicates how much of the total incident sound is absorbed. α = 0 means that no absorption takes place and all incident sound is reflected. At α = 0.5, 50% of the sound energy is absorbed and 50% is reflected. At α = 1, all incident sound is absorbed and there is no reflection.
