The properties of electric fields of hydroacoustic piezoceramic radiators with internal acoustically soft baffels in a wide range of frequencies depending on the size of the baff els have been studied. The studies were carried out taking into account the interaction of physical fields in the process of energy conversion and interaction of the piezoceramic shell and baffel on the acoustic field during the formation of energy in the surrounding space. The analytical relations that describe these physical fields are related to the general solution of three differential equations - the wave equation, the equation of electromechanical oscillations of the electroelastic piezoelectric shell and the equation of state of this piezoelectric shell. The solution of the problem is to solve the problem by means of the known methods of infi nite system of linear algebraic equations concerning the unknown coefficients of decomposition of mechanical and acoustic fields of radiation in the Fourier series. The regularities in the frequency behavior of the total capacitive and dynamic currents of electric excitation of the radiators of hydroacoustic stations and the total, active and reactive input electrical resistance of these radiators are established. The complexity of constructing the matching devices for generators and radiators in the radiation devices of hydroacoustic stations is shown. It is established that by selecting the size of internal baffels it is possible to effectively control the parameters of electric fields of shielded radiators in different frequency ranges of hydroacoustic stations operation. At small sizes of internal baff els and preservation of the sizes of hydroacoustic radiators in the field of low frequencies there are new resonant frequencies which are two times less in size, than the basic resonant frequency of the shielded radiator. At the same time, the new resonant frequencies have greater efficiency in converting electrical energy into acoustic energy. The use of these frequencies increases the range of the hydro-acoustic station
