Abstract
A hydrophone is provided which includes at least four piezoelectric sensors mounted to a central section of syntactic acoustic dampening material as well as a layer of corprene between the piezoelectric sensors and the central section. Each of the piezoelectric sensors includes radially poled piezoelectric cylinders wired in series with inert polycarbonate endcaps and an isolator layer. The piezoelectric cylinders are assembled co-axially. The piezoelectric cylinders are then adhered to the central section and sandwich a layer of corprene. The corprene also adds noise dampening properties.
