A new method of linearity measurements of a PVDF membrane hydrophone was elaborated. High pressure pulses up to 6MPa were obtained in the focus of a concave PZT transducer with the frequency of 3MHz. The method is based on the pressure decrease of these pulses transmitted through metal layers with known acoustic impedances, immersed in water. In this way one obtained pressure changes at constant shapes (spectrum) of the pulses which were measured by means of the hydropbone under investigation. The measurement results confirmed the linearity of the hydrophone up to pressures equal to 2.3MPa. Correlation coefficients of 5 measured relations were in average equal to r=0.994.
