Abstract:The piezoelectric hydrophone widely used in offshore seismic exploration is called pressure-sensitive hydrophone.Its output voltage is directly proportional to the water pressure around it.The circuit equation, transfer function and some formulas for natural frequency, damped coefficient, sensitivity and source impedance are derived by researching into the piezoelectric crystal transducer and equivalent circuit of the piezoelectric hydrophone.The derived transfer function of piezoelectric hydrophone is similar to that of land dynamic geophone;therefore, the pressure-sensitive hydrophone may be considered as velocity geophone.
