Underwater Response Characteristics of Electrostatic Transducers

Abstract

Electrostatic transducers have been used as receivers and transmitters of ultrasonic waves at frequencies up to one megacycle per second. Transducers with solid dielectric are widely used, particularly for ultrasonics in air. It is the purpose of this paper to study the response of one type of these transducers in water, especially the response to the impulsive sound produced by an electrical discharge.
