Abstract

The frequency and phase characteristics of the acoustic fi elds of cylindrical hydroacoustic transducers formed from a piezoceramic shell, an elastic medium and an internal acoustically soft baffl e were performed, depending on the physical characteristics of the fi lling medium. It has been found that by choosing the density and speed of sound propagation in a liquid that fi lls the internal volume of the transducer, it is possible to adjust the spectrum of resonant radiation of hydroacoustic stations (GAS), enriching it in the frequency domain required for the operation of the GAS. As the density and velocity of the sound in the fi lling fl uid decrease, the resonant sound emission propagates far down in the frequency range 0−8000 Hz, while increasing these values − far up in the frequency range 14000−20000 Hz. And all this takes place without changing the overall dimensions of the transducers. It is shown that such parameters of the effi ciency of the GAS as the range of action and resolution are largely determined by the characteristics of the design elements of the hydroacoustic antennas of these GAS.
