What is Baumann Noise about?

This document proposes a simplified method for estimating cavitation noise in control valves based on the observation that cavitation is an aerodynamic rather than hydraulic phenomenon caused by rapid pressure fluctuations. The method models cavitation noise as proportional to inlet pressure to the sixth power and defines curves based on the coefficient of incipient cavitation. It shows good correlation with test data for a wide range of valves and operating conditions. The key benefits are greatly simplify
