Ultrasonic is sound generated above human audible level. In real life, high pitch sound is created by high frequency, and alternatively, the low and base tone is created by low frequency. Frequencies above 16 kHz in general are being considered as ultrasonic. Typical ultrasonic frequencies used for cleaning purpose are from 20 kHz to 80 kHz.
