Annotation The amplitude-frequency characteristics of electric fields in the form of a sensitivity related to external acoustic action of the piezoceramic cylindrical converter are obtained, which is located in a closed wave layer . At the same time, the scattering of a plane sound wave taking into account the reaction of the wave layer, the conditions of electrodiding, the electric loading regime, and the electroelastic properties of the oscillating shell are taken into account. It is shown that the conditions of electric loading lead to changes in the acoustic transparency of the layer. It is established that the control of the parameters of the frequency response is possible by selecting the electrical load of the electronic circuit, which is connected directly to the electrodes of the electroelastic converter, by changing the thickness of the layer (which leads to a change in the wave dimensions of the oscillatory system) and the choice of technological materials.
