The variations in the first resonance frequencies of underwater acoustic transducers such as flexural piezoceramic bars and disks are discussed. The theoretical investigations established the dependence of bandwidth on the length to thickness ratio of the transducer, the type of piezoceramic material and coupling, and piezoceramic thickness and coverage. The measurements of frequency shifts of a transducer depicted the existence of a polarization switch due to combined compressive stress and electric field effects.
