✦ Synopsis

Knowledge of the spatial distribution of intensity loss from an ultrasonic beam is vital to bioeffect predictions such as heating and streaming. A method for calculating the distribution of intensity loss over a finite-amplitude ultrasonic beam is described. The technique demonstrates that the location of peak intensity loss varies considerably with drive level for a plane circular source, as does the overall distribution of intensity loss across the beam. The effects are shown to be less pronounced but still significant for a focused source.

An assessment of the applicability of an acousto-ultrasonic (AU) technique for the monitoring of porous ceramic systems has been carried out. Sintered glass was used as a model system and it was found that the AU parameters, such as normalized ringdown count, normalized pulse width, velocity and fre
