It is shown that one of the approaches to ensuring the multi-functionality of ship hydroacoustic instruments is the transition from several hydroacoustic stations to one multifunctional hydroacoustic complex. For this purpose, it is proposed to replace passive acoustic screens with active electroelastic bodies in these devices, the acoustic properties of which can be quickly controlled with the help of electric voltage. Analytical relations for determining the radiated acoustic energy were obtained for a typical element of hydroacoustic complex, which consists of an electroelastic transducer and an acoustic screen, under the conditions of connectedness of physical fields and processes by the method of connected fields in multi-connected regions. Numerical dependencies of radiated acoustic energy for different spatial directions of radiation and different options for excitation of an active acoustic screen were established by the method of numerical experiment and analysis of its results. Energy results are compared for a typical element and its single transducer.
