Frequency and angular characteristics of the amplitudes and phases of the acoustic fields of cylindrical hydroacoustic transducer formed from piezoceramic shell, an elastic medium and an acoustically soft baffle, depending in the size of the baffles and the distance between the long axes of the shell were made. It is established that such technical implementation of transducers significantly enriches the range of resonance emitting by hydroacoustic stations and extends it away in the low-frequency domain compared to the hydroacoustic stations based on transducers without internal baffles. The number of newly generated frequencies of resonance emitting their placement on the low-frequency (0−6000 Hz), resonance (7000−14000 Hz) and high-frequency (more than 14000 Hz) ranges and the amplitude of the acoustic signals at the frequencies of resonance emitting, regulate by the diameters or distance between long axis of the piezoceramic shell and baffle. However, without changing of the size of the transducers in the low-frequency domain, their resonance frequencies can be 2−5 times less, and the resonance emitting of hydroacoustic signals at the same electric field voltage is comparable or much greater relative to the main resonanсе frequency of the transducers without baffles. Since modern hydro-acoustic stations do not have internal baffles as part of their transducers, the transition in them to the design of transducers with internal baffles should provide an increase in the efficiency of hydro-acoustic stations in terms of the effective implementation of different modes of operation on one hydro-acoustic antenna, increase the energy range of these modes.
