The problem of parametric transformation of the ultrasound into the sound for emitter of small wavesize is examined. The results of theoretical and experimental studies of sound pressure distribution along the axis of the emitter, the radiation pattern for ultrasonic and audio frequencies, the sound level dependent on the type and parameter of amplitude modulation are presented.
