Dear List, Has anyone know of existing acoustic data on these obnoxious tooth cleaning devices? I tried to get data on the web on ultrasonic dental drills/cleaning devices and got nowhere. I would like to have a frequency response curve and a dB reading at some point (preferably in the ear canal of the patient or the technician/dentist). Thank you, Pierre Divenyi **************************************************************************** Pierre Divenyi, Ph.D. Speech and Hearing Research (151) V.A.
