SOUND DETECTION SYSTEM AND INFORMATION PROCESSING DEVICE

A sound detection system includes a plurality of microphones each configured to detect a sound inside a living body and output a sound signal generated based on the detected sound; and an information processing device, the information processing device includes an acquisition unit configured to acquire the sound signal from each of the plurality of microphones, a control unit, and an output unit, the control unit specifies a first position that is a position of a prescribed living body site based on the sound signals acquired by the acquisition unit, estimates a second position that is in a prescribed relative positional relation with the first position, and controls directivities of the plurality of microphones to increase a sensitivity with respect to the second position, and the output unit outputs information generated based on the sound signals acquired by the acquisition unit in a state in which the directivities of the plurality of microphones are controlled to increase the sensitivity with respect to the second position.
