A spherical bubble in a liquid is a nonlinear oscillator that can be set into radial (and surface) oscillations by a sound field. The nonlinear response depends on a set of parameters, mainly the bubble radius, the driving amplitude and the driving frequency. The response is involved. It consists of an intertwined set of nonlinear resonances that besides turning over comprise period doubling sequences to chaos when going up and down in bubble radius, driving frequency or driving amplitude. A prominent feature at higher excitation pressure is the giant response appearing for small bubbles and being the host for single bubble sonoluminescence.
