摘要：
There are intractable problems with computer models of enclosed spaces using geometric acoustic assumptions. A new beam tracing method for finding image-receiver paths using triangular section beams is suggested where the source of these beams is omnidirectional and the beams do not overlap. A method of radiant exchange is proposed that produces a diffuse reverberant tail for an impulse response. These is no sharp division between the two models, rather the two overlap and the emphasis changes from the specular to the diffuse model.
