ABSTRACT

Analytic solutions of two-dimensional problems of emission of sound by a rectangular piezoceramic transducer into an acoustic half space, baffled by a soft or rigid baffle are obtained. The far-field pressure directivity patterns are constructed and found to be in good agreement with experimental data. The efficiency of sound emissions at several normal modes of planar vibrations of the rectangular transducer is estimated.
