BIOLOGICAL SOUND MEASUREMENT DEVICE, BIOLOGICAL SOUND MEASUREMENT ASSISTANCE METHOD, AND BIOLOGICAL SOUND MEASUREMENT ASSISTANCE PROGRAM

摘要

Through the present invention, it is determined with high precision whether one or both of a state of contact with the body surface of a living body and the position of contact of a device with the body surface satisfies a condition necessary for measurement of a biological sound, and the precision of measurement of a biological sound can be enhanced. A biological sound measurement device (1) having a housing (31) for forming an accommodating space SP1 sealed by a body surface S in a state of being pressed against the body surface S, the biological sound measurement device (1) for measuring a biological sound of a living body on the basis of a pressure variation of the accommodating space SP1, is provided with a sound generating unit (35) disposed in the accommodating space SP1, a sound measurement unit (36) disposed in the accommodating space SP1 for measuring reflected sound of sound generated from the sound generating unit (35), and a control unit (4) for determining whether the state of contact or the position of contact of the housing (31) with the body surface S is satisfactory on the basis of the reflected sound measured by the sound measurement unit (36) and issuing notification when it is determined that the state of contact or position of contact is not satisfactory.
