Biological sound analyzing apparatus, biological sound analyzing method, computer program, and recording medium

A biological sound analyzing method comprising:

• an obtaining process of obtaining, by a sensor, first biological sound information, which indicates a change in biological sounds with time;
• a processing process of generating, by a processor, second biological sound information by performing a first process of enhancing first noise information, which indicates noise included in the biological sounds, on the first biological sound information;
• a calculating process of calculating, by the processor, correlation information, which indicates a correlation in adjacent periods of the second biological sound information;
• and
• an outputting process of outputting, by a display, second noise information, which indicates continuous noise included in the biological sounds, on the basis of the correlation coefficient.

A non-transitory computer-readable medium having executable instructions executable by a processor, the instructions comprising:

• obtaining first biological sound information, which indicates a change in biological sounds with time;
• generating second biological sound information by performing a first process of enhancing first noise information, which indicates noise included in the biological sounds, on the first biological sound information;
• calculating correlation information, which indicates a correlation in adjacent periods of the second biological sound information;
• and
• outputting second noise information, which indicates continuous noise included in the biological sounds, by using the correlation coefficient to calculate a continuous sound tendency indicative of a characteristic of the continuous noise.
