SOUND CONTROL DEVICE, SOUND CONTROL METHOD, SOUND CONTROL PROGRAM, AND RECORDING MEDIUM ON WHICH SOUND CONTROL PROGRAM IS RECORDED

摘要

When a moving body (MV) is stopped, a sound output control unit (750A) determines whether a person is detected in the surroundings of the moving body (MV) by a human detection unit (730). When the results of the determination are positive, the sound output control unit (750A) determines whether a leaking sound of an inside sound to the outside of the moving body (MV) can be recognized by a detected person on the basis of the inside sound and an outside sound detected by a moving body outside sound detection unit (710) and a moving body inside sound detection unit (720) for the moving body (MV). If the results of this determination are positive, the sound output control unit (750A) extracts environmental sound that does not include the leaking sound on the basis of the outside sound and inside sound. Furthermore, the sound output control unit (750A) carries out control in which environmental sound is output by a sound output unit (790). A sound output unit (210) outputs environmental sound according to control by a control unit (150A). Therefore, environmental sound that does not annoy people in the surroundings of the moving body (MV) is output and the degree of recognition of leaking sound outside of the vehicle can be reduced.
