Design and test of cylindrical high hydrostatic pressure hydrophone

HE Tao;Hangzhou Applied Acoustic Institute;  
This paper introduces a high hydrostatic pressure hydrophone which is used in the 20 Hz–20 kHz band and the maximum depth is 5000 meters. The sensor uses thick wall piezoelectric circular tube and high strength composite foam to decouple. Through reasonable design of the structure, the hydrophone has high pressure resistance. The sensitivity of the hydrophone under normal and different pressures is tested. The test results show that the sensitivity of the receiver at atmospheric pressure is flat. In the 0.1 MPa–50 MPa pressure range, the maximum change of the sensitivity of hydrophone at low frequency is less than 2 dB, which indicates that the hydrophone has good pressure stability. It can be widely applied in deep resource survey and deep sea communication.
