Abstract
A piezoelectric composite of lead titanate powder and chloroprene rubber is formed to cable-like element. Receiving sensitivity of prototype hydrophones employed the element was -203 dB(0 dB: 1 V/µPa) at frequencies below 1 kHz. Accordingly, sea-going low frequency hydrophone employed the element was fabricated and applied for measurement of the sea ambient noise. In addition, it is confirmed that Langevin type hydrophone employed the composite reduces resonant frequency and mechanical Q compared with conventional piezoelectric ceramic hydrophone.
