Sabin (unit)
From Wikipedia, the free encyclopedia
The Sabin is defined as a unit of sound absorption. One square meter of 100% absorbing material has a value of one metric Sabin. The unit is named in honor of Wallace Clement Sabine. The total adsorption in sabins can be calculated by:
A=S1α1+S2α2+...+Snαn=ΣSiαi
where
A = the absorption of the room (m2 sabin)
Sn = area of the actual surface (m2)
αn = absorption coefficient of the actual surface
