UNDERWATER SOUNDTRANSDUCER CALIBRATION FACILITY FOR THE 10- TO 4000-Hz FREQUENCY RANGE AT HYDROSTATIC PRESSURE TO 10,000 psig
Abstract
A new controlled-environment facility operating on the principle of active-impedance termination in a rigid-walled tube now provides the means of calibrating a wide variety of underwater sound transducers in the increasingly important frequency range 10 to 4000 Hz at static pressure to 10,000 psig and temperature from 3 to 45C. This report describes the theory, limitations, and mechanical features of the facility and presents examples of both primary and secondary calibrations of transducers in the tube and in a free field.
