ELECTROACOUSTIC TRANSDUCERS FOR A 10,000-psig UNDERWATER SOUND TRANSDUCER CALIBRATION FACILITY FOR THE FREQUENCY RANGE 10 TO 4000 Hz

Abstract

The design and construction of the terminal and source transducers, a reciprocal spherical piezoelectric ceramic transducer, and the probe hydrophones that are part of a new USRD measuring facility are described. The facility is used for the calibration of underwater sound transducers in the frequency range 10 to 4000 Hz at hydrostatic pressure to 10,000 psig and controlled temperature from 3 to 45 deg C. It operates on the principle of active-impedance termination in a rigid-walled, water-filled tube.
