Abstract

Acoustic emission (AE) from a single bubble trapped in a water/glycerine mixture by an acoustic standing wave is reported. The AE has been measured by a calibrated needle hydrophone in different regimes of bubble dynamics. The hydrophone response shows a large amplitude AE pulse which corresponds to the principal collapse along with smaller amplitude pulses which can be associated with the after bounces of the bubble just after the initial collapse. The pressure amplitudes of the AE are much weaker below the sonoluminescing regime. A light scattering experiment has been carried out to study the bubble dynamics, and the results are compared to those of AE measurements
