In this paper, a laser interferometer hydrophone is made according to Michelson interference principle. By tracking compensation, the performance of the hydrophone is effectively improved and its anti-interference ability is improved. Through theoretical analysis of the hydrophone, it is found that the vibration film will bring errors to the measurement results of the hydrophone, but the measurement error can be reduced by selecting different types of vibrating membrane. In addition, the laser interferometric hydrophone is applied to the noise measurement of offshore marine environment. The offshore ocean observation experiment shows that the laser interferometric hydrophone can measure the noise parameters of the marine environment, and has good frequency band adaptability and accuracy.
