Bubbles, ultrasound, and swimmer safety

Résumé

The benefits of ultrasonics in algae control have been well known [1]. The transmit frequencies used to study this application have been as low as 20 kHz and as high as 1.7 MHz. Most commercial equipment operates in the lower ultrasonic range. There have been speculations about the physical mechanism behind the algae eradication, specifically about the role of cavitation. Furthermore, the consequences for swimmers in water subjected to ultrasonic treatment have been unknown. In this study, we investigate the role of cavitation as potential danger for swimmers. Furthermore, we give an estimate of swimmer safety radii, based on current regulations.
