Abstract:
The patent describes a piezoelectric ceramic transducer assembly for broadband noise-measuring hydrophone. A longitudinally polarized lead zirconate-titanate cylinder provided with end caps is sealed by O-rings within a circumferentially polarized lead zirconate-titanate cylinder providing high sensitivity, smooth response, omnidirectionality, and stability with temperature and hydrostatic pressure variations.
