The collapse of single bubbles and approximation of the far-field acoustic emissions for cavitation induced by shock wave lithotripsy [PDF]

open access: yes, 2011
Recent clinical trials have shown the efficacy of a passive acoustic device used during shock wave lithotripsy (SWL) treatment. The device uses the far-field acoustic emissions resulting from the interaction of the therapeutic shock waves with the tissue

Revisiting Oto-Acoustic Emissions

open access: yesProceedings of Singapore Healthcare, 2015
Oto-acoustic emissions (OAEs) are an audiometric diagnostic test that allows quick objective measure of hair cell function in the inner ear. It is a reflection of hearing function at the interface of conductive and sensorineural components in the human ...
