Underwater Sound Measurements at High Hydrostatic Pressures,

Abstract

Electroacoustic transducers used in underwater sound work may exhibit appreciable changes in transmitting and receiving responses when operated under high hydrostatic pressures. Changes in response as great as 6 db at 300 pounds per square inch have been measured. Several curves which show the results of measurements on typical instruments are presented. Response hysteresis with direction of pressure change and shift of resonance frequency are two of the effects noted during tests at high pressures. The features of construction of two pressure-stable transducers which have been developed are given, and the transducer characteristics are shown in four Figures. (Author)
