Abstract

The results of an experimental study of the penetration of highly directional acoustic beams into bottom sediments were recently reported by Muir, Horton, and Thompson [J. Sound Vib. 64, 539–551 (1979)]. Of special interest was the behavior of a narrow beam generated by a parametric source. We have considered this problem theoretically. Simplified equations for the reflected and refracted beams at the water-sediment interface are derived and solved analytically subject to the nondissipative boundary conditions. The range of validity is discussed. Results are presented that seem to explain the experimental observations.
