Measurement of cavitation noise in ultrasonic baths and ultrasonic reactors. | Status: Current

1 Scope This document, which is a Technical Specification, provides a technique of measurement and evaluation of ultrasound in liquids for use in cleaning devices, equipment, and ultrasonic reactors. It specifies

• • the cavitation measurement at frequencies between harmonics of the operating frequencyf0,
• • the cavitation measurement derived by integrating broadband cavitation noise energy,
• • the cavitation measurement by extraction of broadband spectral components.

This document covers the measurement and evaluation of cavitation, but not its secondary effects (cleaning results, sonochemical effects, etc.). Further details regarding the generation of cavitation noise in ultrasonic baths and ultrasonic reactors are provided in Annex A.
