摘要

Theoretical expressions derived. previously describing the exact pressure field produced at close ranges by an tvpulalva sound aourca In a fluid near a two-layer aolid Interface are evaluated by computer techniques to obtain the praaaura as a function of them Waveform, obtained experimentally from .models are presented that aubatantlate the theoretical reauita. The above theory la also extended so that water surface reflectiona are feliowed. This investigation nay be of assistance in the study of low-frequency sound propagation near the ocean floor.
