Transmission of Sound Through a Randomly Rough Air-Sea Interface.
Abstract
The Helmholtz integral and the Kirchhoff approximation have been used to develop predictions for the transmission of sound through a rough air-sea interface. A model study was conducted with wind-driven surfaces generated in a large anechoic tank. The frequencies used were scaled to be equivalent to low audio frequencies with moderate seas. The coherent component of the transmitted acoustic intensity was tested for exponential decrease with increasing values of the roughness parameter. An empirical correction factor was determined to give a corrected roughness. (Author)
