Abstract
PURPOSE: One piezo-electric vibrator contacts the bottom of the conductive case which contacts the body being tested. The other piezo-electric vibrator contacts any place other than the bottom of the case to eliminate the acoustic noise which propagates through air and when the above is combined with a differential amplifier, it is possible to eliminate electrical noise.
