Acoustic cavitation thresholds and cyclic processes

There is currently renewed interest in cavitation thresholds in connection with industrial and medical applications of ultrasound. This paper is a review of the theory relating to thresholds. In particular, it shows how these thresholds can be located using simple approximate formulae. The paper also examines a number of interesting cyclic processes that take place around the thresholds. The paper is an expanded form of recent seminars.
