Acoustic cavitation, the primary mechanism of sonochemical effects, is known to be induced more easily by standing waves than by progressive waves. It has been found that acoustic cavitation can be an order of magnitude enhanced by superimposing the second harmonic on the fundamental. Significant synergistic effects between the fundamental and the second harmonic were observed in both in vitro and in vivo experiments employing a progressive wave field. Second-harmonic superimposition induces in… CONTINUE READING
