WebFormula for Sabins: a = Σ S α. Where: Σ = sabins (total room absorption that exists at a given frequency) S = surface area of material (feet squared) α = sound absorption coefficient that exists at a given frequency or the NRC. After the calculation of a, one can make use of the Sabine Formula for calculating the reverberation time.
