Abstract:
In comparison to the problems of room acoustics in measuring the diffuseness of reverberant sound, the problem in underwater sound is in determining the directionality and spatial distribution of the sound field. The ocean is a large stratified medium bounded by a free surface and a hard bottom with relatively low attenuation, so that the sound propagates very well for long distances and by several different paths. Background sound is generated at the free surface as a result of wind-wave interaction and by ships, in the medium by whales and other marine life, and in the bottom by seismic sources. In this paper, the theory, advantages, and limitations of the techniques used—such as linear arrays, digital correlators, and theoretical models—are discussed.
