A hydrophone (10) for immersion in a liquid body defining a depth-dependent static pressure and a dynamic pressure. The hydrophone (10) includes a pressure-bearing element (11) for exposure to the liquid body; a motion sensor (13) spaced apart from the pressure bearing element (11); and a dilatant coupling material (14) disposed intermediate the pressure-bearing element (11) and the motion sensor (13) so as to mechanically transmit movements substantially corresponding to the dynamic pressure from the pressure-bearing element (11) to the motion sensor (13). The dilatant coupling material (14) does not transmit movements to the motion sensor (13) that substantially correspond to the depth-dependent static pressure.
