Abstract	In this paper, the cylindrical PZT acoustic-pressure hydrophone has been researched. Based on the analysis of cylindrical piezoelectric ceramic pipe free vibration and statically receiver theory, the sensitivity of hydrophones covered with plate, whose have three different polarization models, can be got. By comparison, the tangential polarized ceramic pipe has the relatively high sensitivity, and at the same time, the hydrophone sample has been fabricated based on the finite element method. The experimental results show that the working frequency band of hydrophone sample is 30 Hz–40 kHz, the average acoustic pressure sensitivity is about ∼182dB within 30 Hz–10 kHz. There are some difference in resonance frequency and the sensitivity between the result of simulation and test because of the simplification of structure in simulation.
