Abstract
A series of omnidirectional reference transducers for the frequency ranges from 1 Hz to 200 kHz when used as a hydrophone and from 2 to 200 kHz when used as a projector has been developed by the Naval Research Laboratory's Underwater Sound Reference Detachment in Orlando, Florida. The sensitive elements are all piezoelectric lead zirconate - lead titanate PZT-4 hollow spheres encapsulated in polyurethane.Keywords
