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.
