| Outline of Final Research Achievements |
We have studied measurement control on acoustic cavitation by using subharmonics and broadband noise that are acoustic signals generated from cavitation bubbles.
As the result, subharmonics generated at generation and collapse of the bubbles, and broadband noise generated at expansion and contraction of the bubbles. There is a possibility that behavior of the bubbles can be measured and controlled by the acoustic signals generated from the bubbles. Also, broadband noise may be used as index on performance evolution of ultrasonic cleaning.
