1967 Review of Sound Division Program
Abstract
In an effort to enhance the Navy's capability in Sonar, the Acoustic Research Branch singles out for study, specific acoustic situations which have not heretofore been described with sufficient experimental or mathematical precision. Currently there are five studies underway; (1) experimental confirmation of the relationship between the sound rays and the sound speed' profile in the ocean; (2) precision measurement of sound speed and absorption in sea water and in other acoustic media of Sonar importance, as functions of pressure, temperature and salinity; (3) refined experimental measurement and mathematical confirmation of findings essential to a detailed description of acoustic reflection from special objects in water; (4) description of the forces incident to flow of water about submerged objects inducing vibrations which emit sound and the physical description of the vortices in which the forces arise; (5) processes of information storage and retrieval ranging from the quality control of magnetic tape to instrumentation for automatic programming and data processing.
