Abstract:

An acoustically transparent, medium-power, bidirectional sound source has been designed and built for use in the anechoic tank facility at frequencies from 0.4 to 10 kHz, hydrostatic pressures from 0 to 1000 psig, and temperatures between 3 and 30C. It consists of a planar 6x6 array of PZT-4 elements the over-all dimensions are 19.5 in. wide, 26 in. long, and 1.5 in. thick. The transmitting current response is about 46 dB re 1 millibarA at 0.4 kHz and rises 6 dB per octave to about 73 dB at 10 kHz. The output is linear with driving voltage to 200 V rms. The transducer also can be used as hydrophone the free-field voltage sensitivity is about -100 dB re 1 Vmillibar at frequencies from 1 Hz to 10 kHz.
