THEORETICAL AND EXPERIMENTAL PROPAGATION OF ELASTIC WAVES IN A FLUID-SOLID-SOLID LAYERED SYSTEM.

Abstract

Theoretical expressions derived previously describing the exact pressure field produced at close ranges by an impulsive sound source in a fluid near a two-layer solid interface are evaluated by computer techniques to obtain the pres sure as a function of time. Waveforms obtained experimentally from models are presented that substantiate the theoretical results. The above theory is also extended so that water surface reflections are allowed. This investigation may be of assistance in the study of low-frequency sound propagation near the ocean floor. (Author)
