Summary:PROBLEM TO BE SOLVED: To stably collect non-audible murmur (NAM) for a long time without any exclusive mounting objects or with simple mounting objects by using a non-audible murmur microphone. SOLUTION: Conductive sound is not collected by directly attaching the NAM microphone onto a skin surface directly below a mastoid process. Vibration sound conducted (superconducted) via the internal soft tissue of fingers 103-105 is collected by the NAM microphone 101 once. The vibration sound can be stably collected for a long time from an optimum place directly below the mastoid process without using any special devices via the fingertip of a person who attaches the NAM microphone.
