BIOLOGICAL SOUND ANALYSIS DEVICE, BIOLOGICAL SOUND ANALYSIS METHOD, COMPUTER PROGRAM, AND RECORDING MEDIUM

WIPO Patent Application WO/2017/130417

A1

A biological sound analysis device comprising: an acquisition means (100) that obtains first biological sound information indicating chronological changes in biological sound; a processing means (230) that generates second biological sound information by performing a first processing on the first biological sound information, said processing highlighting first noise information indicating noise included in the biological sound; a calculation means (240) that calculates correlation information (P(t)) indicating correlation during adjacent time periods in the second biological sound information; and an output means (250) that, on the basis of the correlation information, outputs second noise information indicating continuous noise included in the biological sound. As a result, continuous noise included in the obtained biological sound can be suitably analyzed.
