Investigation of the cross-correlation of spectral components of cavitation noise

The results of the study of the cross-correlation of the spectral components of cavitation noise (CN), in particular, the fundamental frequency, i. e. frequency $f_0$ of the ultrasonic field, subharmonics, harmonics of the fundamental frequency, the continuous component of the CN, and a number of others are proposed. It has been established that the fundamental frequency correlates weakly with other NC components, i. e. the relationship $f_0$ with the other frequencies is characterized by a low correlation coefficient. A linear relationship has been found between the harmonics of the fundamental frequency, the continuous component of the spectrum, and the integral power of cavitation noise.
