Abstract: The invention utilizes a multiple frequency ultrasound generator driving a multiple frequency harmonic transducer array to improve cleaning and processing effects while eliminating damage to parts being cleaned. An AC switch and circuitry to modify the output of an ultrasound generator in combination with techniques such as random AM and FM signals are used to produce ultrasound waves that have no single frequency components which eliminates exciting parts being cleaned into resonance. Generator signals that increase cavitation efficiency and that have successive time periods with predominately stable cavitation and predominantly transient cavitation further improve the performance of the cleaning or processing systems.
