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