Sound detection system and information processing device

A sound detection system comprising:

• a plurality of microphones, each of the plurality of microphones configured to detect a sound inside a living body and output a sound signal generated based on the detected sound;
• and
• a computer that:
• acquires the sound signals from the plurality of microphones;
• specifies a first position that is a position of a prescribed living body site based on the acquired sound signals;
• estimates a second position in the living body site, the second position being different than the first position and in a prescribed positional relation with the first position, and wherein the second position in the living body produces a sound that is relatively weaker than a sound being produced by the first position;
• controls directivities of the plurality of microphones to increase a sensitivity with respect to the second position;
• and
• outputs information generated based on the acquired sound signals in a state in which the directivities of the plurality of microphones are controlled to increase the sensitivity with respect to the second position.

A method for detecting sound inside a living body, the method comprising:

• affixing a plurality of microphones to the living body, each of the plurality of microphones configured to detect a sound inside the living body and output a sound signal generated based on the detected sound;
• acquiring, by an information processing device, the sound signals from the plurality of microphones;
• specifying, by the information processing device, a first position that is a position of a prescribed living body site based on the acquired sound signals output;
• estimating, by the information processing device, a second position in the living body site, the second position being different than the first position and in a prescribed positional relation with the first position, and wherein the second position in the living body produces a sound that is relatively weaker than a sound being produced by the first position;
• controlling, by the information processing device, directivities of the plurality of microphones to increase a sensitivity with respect to the second position;
• and
• outputting, by the information processing device, information generated based on the acquired sound signals in a state in which the directivities of the plurality of microphones are controlled to increase the sensitivity with respect to the second position to an output unit.
