central bolt. In this model the frequency response of the transducer is studied to determine structural and acoustic response of the device such as deformation, stresses, radiated pressure, sound pressure level, far-field beam pattern, the transmitting voltage response (TVR) curve, and the directivity index (DI) of the sound beam.
