STUDY ON THE VARIATION LAW OF SENSITIVITY OF HYDROPHONE UNDER THE CONDITION OF ACOUSTIC BAFFLE
Aiming at the influence of anti-acoustic baffle on the acoustic characteristics of hydrophone,the sound field model of hydrophone under the influence of anti-acoustic baffle is established by using finite element software,and the sensitivity variation law is analyzed.The simulation results show that the anti-acoustic baffle and the hydrophone can be placed at 45°,and the former can increase the sensitivity of the latter by 6dB in a certain frequency range.This frequency range varies with the change in the anti-sound coefficient of the baffle and the distance between the hydrophone and the baffle.The research results have guiding significance for designing high-sensitivity hydrophones in the future.
