Abstract
An attempt is made to develop a geometric theory of reverberation without bringing in the simplifying assumptions that are required by statistical considerations. The reverberation phenomenon is simulated on a digital computer by the ray tracing method. Experimental investigations to check the validity of the computer model are described. Large disagreements are found between the computed and experimental results. Consequently, the computer model is re-examined and modified to incorporate the scattering of sound that occurs at the edges and corners of an enclosure. Good agreement is reported between the modified computer results and the experimental results in situations where the absorbing material covers the enclosure surface(s) completely.
