This is to detect all of the CKK sounds lost at the time when the sound would have originally been generated from the h'11th distance from the previous position. That is, the sound sensor i11 built into the cuff band detects the arterial sound of the upper arm of the human body, and the output signal of the sound sensor i11 as shown in FIG.
