A study of the relationship between the spectral characteristics of cavitation noise and the intensity of sound luminescence (SL) in the field of a focusing emitter was carried out. It was found that the highest degree of correlation with the SL intensity of the parameters studied is characteristic of the broadband component of cavitation noise, i.e., the intensity of the total output signal of the sensor minus all harmonics and subharmonics. This result allows us to conclude that the wide-band component of cavitation noise is generated by collapsing cavities and, therefore, can be used as an indicator of the level of transient cavitation activity.
