The present invention is a biometric sound testing device which estimates the state of a living subject with precision by obtaining biometric sound, and is provided with: a first biometric measurement unit (101) which generates a first biometric sound signal for a first subject portion of the organism a second biometric sound measurement unit (102) which generates a second biometric sound signal for a second subject portion, a subject portion positioned closer to the sound source of the biometric sound than the first subject portion a power ratio calculating unit (304) which calculates the power ratio of the first biometric sound signal in relation to the power of the second biometric sound signal a disease gain calculating unit (305) which calculates, as one of the biometric sound characteristics, the characteristic index of the transmission of biometric sound in the living subject, by performing a calculation that reduces the impact of the inspiratory flow rate and/or body build of the living subject on the power ratio a power calculation unit (301) which calculates the first power, the power of the second biometric sound signal occurring in the first frequency band a malady high frequency power ratio calculating unit (303) which calculates the sound source characteristic indicator of the biometric sound as another one of the biometric sound characteristics, by performing a computation that reduces the impact of the inspiratory flow rate and/or body build of the living subject on the first power.Cette invention concerne un dispositif danalyse des sons biométriques qui estime létat de santé dun sujet vivant avec précision par obtention dun son biométrique, ledit dispositif danalyse comprenant : une première unité de mesure biométrique (101) qui génère un premier signal sonore biométrique pour une première partie de lorganisme du sujet une seconde unité de mesure biométrique (102) qui génère un second signal sonore biométrique pour une seconde partie du sujet, ladi
