This paper finds that the treatment efficiency of ultrasound wave at combined frequencies of low and high excels other fashion ultrasound wave. The combined frequencies ultrasound wave with 28 kHz and 840 kHz can compensate others trough each other and eliminate stationary wave and can make furthest effect of cavitate in liquid anywhere.
