摘要： A sound processing system measures one or more periauricular muscle signals from one or more periauricular muscles of a user. Additionally, the sound processing system computes, based on the periauricular muscle signals, an estimate of an angle corresponding to a direction of a current auditory attention locus of the user with respect to a reference point or plane. The sound processing system controls, based on the estimate of the angle, an operating characteristic of the sound processing system.

摘要： The present disclosure relates to a method and system for generating personalized audio space in vehicle. Information related to user in each region of the vehicle is collected and analyzed to determine direction of first directional speakers associated with corresponding region. An audio space boundary for each region is identified based on the direction of first directional speakers in the corresponding region. Further, the proposed method renders first sound wave of a user selected audio using first directional speakers in the region and transmits a second sound wave corresponding to first sound wave in the region using second directional speakers associated with the corresponding region. The second sound wave restricts rendering of the first sound wave beyond the audio space boundary of the one of the one or more regions to generate the personalized audio space in the vehicle.
