Abstract
Sabine's formula T = 55.3V/avs yields finite values for the period of reverberation even when the coefficient of absorption is unity. This formula is a first approximation to that developed by Norris T = −24V/vs Log10 (1−a); the latter yields T=0 for a=1. An error in the interpretation of the fundamental differential equation in the derivation of Sabine's formula is demonstrated. Another mode of attack permits a more correct analysis of a room under certain specified distributions of absorbing material.
