Publication number: 20200252724Abstract: The technology described in this document can be embodied in a method that includes receiving information indicative of a volume setting corresponding to each listening zone of a plurality of listening zones. The method also includes generating a zone-specific adjustment signal for each of the plurality of listening zones, wherein the zone-specific adjustment signal for a given listening zone accounts for a cross-zone effect associated with a volume setting corresponding to another listening zone, and is configured to adjust an output of corresponding zone-specific circuitry. The method further includes generating an additional adjustment signal configured to adjust an output of a cross-zone equalization filter. The output of the cross-zone equalization filter is configured to generate a target acoustic distribution across multiple listening zones.Type: ApplicationFiled: January 6, 2020Publication date: August 6, 2020Inventors: Jeffery R. Vautin, Michael S. Dublin, Eduardo T. Salvador, Charles Oswald

Patent number: 10056068Abstract: An audio system includes a plurality of near-field speakers arranged in a listening area. A plurality of cross-talk cancellation filters are coupled to the speakers. The speakers and the filters are arranged to provide first and second listening zones in the listening area such that audio from the first listening zone is cancelled in the second listening zone and vice versa. The system also includes at least one audio source providing audio content. Volume-based equalization circuitry receives an audio signal representing audio content for the first listening zone from the audio source and controls a volume adjustment applied to the audio signal to control a volume of audio in the first listening zone. The circuitry limits attenuation or amplification of a first frequency portion of the audio signal when a volume setting differential corresponding to a difference between volume settings for the first and second zones exceeds a predetermined value.Type: GrantFiled: November 14, 2017Date of Patent: August 21, 2018Assignee: Bose CorporationInventors: Charles Oswald, Eduardo T. Salvador, Jeffery R. Vautin, Michael S. Dublin, Daniel Ross Tengelsen, Christopher B. Ickler
