An electroacoustic transducer which uses polyvinylidene fluoride (PVF2) as the piezoelectric element is investigated for its suitability as an acceleration insensitive hydrophone. The fundamental construction concept involves attaching concentric layers of PVF2 to a mechanically compatible end-capped cylinder. An expression for the electroacoustic sensitivity is developed and compared to measured acoustic data for a variety of hydrophone configurations. The axial acceleration sensitivity is measured and compared to one type of piezoelectric ceramic hydrophone.
