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.

Sound reproduction system and sound quality control method

A sound reproducing apparatus includes a speaker, a microphone, and at least one processor. The at least one processor performs a process that includes hear-through processing and noise cancellation processing. The process also includes a storage task and a reading task. When detecting an occurrence of the trigger, the reading task reads control information of the event information of which execution is instructed by the trigger. The reading task also executes the hear-through processing and the noise cancellation processing in the signal processing task.

Sound reproducing apparatus, sound reproducing method, and sound reproducing system

An acoustic device includes binaural speakers, a storing portion for storing a plurality of head-related transfer functions, and a signal processing portion for processing a sound signal with a head-related transfer function. Two or more function candidates are selected from the plurality of head-related transfer functions. Prescribed test sounds are emitted from the speaker. A function candidate to apply to the user is selected based on a discrepancy between a user-perceived location direction and the sound generation location direction for each function candidate.
