The invention utilizes multiple frequency sound in liquids to improve the cleaning or processing effect. The sound frequencies are produced in two or more non-overlapping continuous frequency ranges. The sound frequencies are controlled to change frequency within the frequency ranges and the sound frequencies are programmed by a digital code to jump amongst the frequency ranges. The sound frequencies may change continuously within the frequency ranges, and the sound frequencies may jump discontinuously from one frequency range to another. The frequency ranges may also be within different, non-contiguous and non-overlapping frequency bands.
