OBSERVATIONS OF THE SOUND FIELD IN THE DEEP SEA,

Abstract

The acoustic structure of the deep sea at ranges out to 110 miles was examined at different ranges, depths and frequencies by means of explosive charges dropped from an aircraft and recorded by a deep ship-borne hydrophone. The expected sequence of convergence half-zones was obtained, even at frequencies as low as the 25-100 Hz band. At all frequencies better transmission was found when both source and receiver lie well within the deep sound channel. (Author)
