Abstract
A physiological sound examination device which supports estimation of a state of a living body includes a first physiological sound measurement unit; a second physiological sound measurement unit; a power ratio calculation unit which calculates a power ratio which is a ratio of first physiological sound signal power to second physiological sound signal power; and an illness-related gain calculation unit which calculates a transfer-characteristic of the physiological sound in the living body by computing the power ratio. A power calculation unit which calculates first power which is the second physiological sound signal power in a first frequency band; and an illness-related high frequency power ratio calculation unit which calculates a sound-source-characteristic of the physiological sound by computing the first power. The computing is performed to reduce an influence of the respiratory flow velocity and/or the size of the living body.
