Some Results on Ray-Acoustic Intensity Calculations.
Abstract
From the differential equations governing variables sufficient for the calculation of geometric ray acoustic intensity in a horizontally stratified medium, deductions can be made concerning the properties of the acoustic intensity field due to a point source. An investigation is made of the relationship between the intensity at a receiver from a given point source and the intensity when source and receiver positions are interchanged. It is shown that the intensity in the one situation is equal to that in the other times the ratio of the squares of the sound speeds at the two depths, provided that reflections are from perfectly reflecting horizontal surfaces and that the profile of the speed of sound is continuous to the first derivative. A simple general relationship between intensities does not exist if either of these conditions is not met. Secondary investigations are made relevant to the numerical computation of intensities.
