AN ANALYTICAL STUDY OF SOUND CHANNEL RAY PATHS.

Abstract

Based on a bilinear velocity profile an analytic description of the major properties of sound channel rays is given. In particular both a qualitative and quantitative description of the arrival structure is given, and an expression is developed giving the number of connecting rays between a source on the axis and a receiver off axis. By reciprocity the latter result also describes the number of connecting rays between an off-axis source and an on-axis receiver. This latter result is extremely useful in calculating volume reverberation in any model which makes use of ray counting to evaluate the reverberation level. (Author)
