✦ Synopsis
There are intractable problems with computer models of enclosed spaces using geometric acoustic assumptions. A new beam tracing methodfor 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. There is no sharp division between the two models, rather the two overlap and the emphasis changes.from the specular to the diffuse model
