The radial and translational motion of single cavitation bubbles interacting with alternating gradients of sound pressure (SP) and among themselves are studied based on analysis of high-speed video data, cavitation noise spectra (CN), and computer modeling. The dynamics of the cavitation field, the physical causes of intense periodic motion for unstable cavities, and the spectral characteristics of CN were studied experimentally and numerically. It was found that, for a given static pressure, development of the cavitation zone is determined by the gas content and viscosity of the fluid.
