Computer Programs for Underwater Sound Fields Due to Airborne Sources

Abstract

An aircraft flying over water produces a significant underwater sound field in the water directly beneath it. Acoustic ray theory can be used to obtain a useful approximate description of the underwater sound field in terms of sound pressure levels. Details of the theory are presented. Computer programs which implement the theory are documented. The results include time histories of acoustic signal angles of arrival at the underwater receiver; time histories of sound pressure levels received at various depths; and equipressure contour descriptions of the underwater sound field.
