ABSTRACT:
A pressure-sensitive improved acceleration-cancelling hydrophone assembly and transducer unit for inclusion therein, each transducer unit being made of glass and metal parts hermetically sealed together with no exposed plastic, each sealed unit containing paired piezoelectric wafers mounted inside the sealed unit in opposed relationship and electrically interconnected such that pressure forces combine in the output signal but acceleration forces cancel, and the hydrophone assembly comprising a barrel in which one or more of these transducer units are mounted in vibration-isolated relationship, the mountings engaging the transducer units at surfaces thereof which are least likely to couple vibrations to the piezoelectric wafers.
