Abstract: Very recently, a new-type ultrasonic motor, which in principle would be quite different from the motor that has been used and that has utilized the mutual action between current and magnetic fields, has being practiced in the world. Generally speaking, whatever the rotatinal machine would be, it has to say quite necessity that the machine would produce some volumes of noises, aloud. Although we have investigated some points of the problem concerning to the matters mentiond above and in case of ultrasonic motor it would be considered that its noise-level would be very low, we have clarified the characters and features of the noise that would occured by the sources of mechanical structures and high-frequency currents. In particular, we would reported on the results of analyzing its frequency-spctrums.
