The invention relates to a hydrophone device for measuring pressure in marine seismic tests. The hydrophone comprises, in a hydrophone body 1 of flexible material, a rigid support body 2, making it possible to make with the hydrophone body 1 a pressure-transmission chamber. Manometric means 4 are mounted in the rigid body 2, the sensitive surface 20 of the latter being in contact with the medium of the pressure-transmission chamber 3. Mechanical pressure-wave filtering means are provided, the filtering means 5 ensuring transmission and filtering of the test pressure waves and the static pressure of the medium towards the sensitive face of the manometric means 4. Application to marine seismic tests for determining the static pressure and the depth of immersion and for detecting test pressure waves. <IMAGE>
