Sound reproduction system and sound quality control method

A device system includes an acoustic device, a sensor, and a sound processor. The acoustic device is configured to be worn by a user. A sensor is configured to detect a movement of a shielding object. The sound processor is configured to generate sound with a first sound quality for a block state in...

description	A device system includes an acoustic device, a sensor, and a sound processor. The acoustic device is configured to be worn by a user. A sensor is configured to detect a movement of a shielding object. The sound processor is configured to generate sound with a first sound quality for a block state in which the shielding object blocks a virtual sound source localized on an opposite side of the shielding object and emit the sound from the acoustic device. The sound processor is further configured to change a sound quality of the sound from the first sound quality to a second sound quality for a non-block state in which the shielding object does not block the virtual sound source, in response to the sensor detecting that the shielding object moves from a position blocking the virtual sound source.
