The problem of the sound reception by means of cylindrical transducer in the circular layer is considered in "through" formulation. Electroelastic properties of piezoceramic shell and the transition layer was taken into account in the solution of declared problem. Features of formation of the amplitude frequency characteristics of multimode piezoceramic receiving transducer with a wave layer are considered for different types of electrodes. In this case the amplitude of the mode components of voltage to frequency characteristics can be adjusted by selecting the type of the electrode and by choosing shielding materials.
