Abstract
The widely used reverberation time formula due to Eyring was derived on the assumption of step-wise drops in the energy level of a diffuse sound field. The argument, besides being difficult to follow, was not justified from the statistical notion of a diffuse field. It is found that Eyring's formula can be extracted from a difference equation based on an energy principle which preserves the continuous nature of the decay process. Interpretations of the average absorption coefficient are also given.
