Abstract : The patent relates to a pressure sensitive hydrophone assembly which provides an undiminshed acoustic sensitivity while discriminating against waves induced in the material surrounding the hydrophone elements by flow and/or vibrational excitation. The hydrophone comprises a ceramic element surrounded by a rigid barrier and an elastic material inside the rigid barrier which is constructed to preclude the arrival of undesired forces at the ceramic element.
