Auralization of information has higher time resolution than visualization. We focus on flesh conduction to acquire human body sound sensitively. Flesh conduction is a phenomenon to provide an effect as if a microphone is implanted in body by covering a diaphragm with material of which acoustic impedance equivalent with that of human body. This paper describes new multichannel measurement system to map body sound with flesh conduction microphone. This system comprises of flesh conduction microphone, 4ch amplifier and analysis software. Authors tested the system by use of acoustic phantom and showed superiority to stethoscope in measuring low audiofrequency range (20〜100[Hz]). And we demonstrate that the system can acquire body sound from 4 positions on the body at the same time.
