Patent number: 9591410Abstract: A hearing assistance device includes two transducers which react to a characteristic of an acoustic wave to capture data representative of the characteristic. The device is arranged so that each transducers is located adjacent a respective ear of a person wearing the device. A signal processor processes the data to provide relatively more emphasis of data representing a first sound source the person is facing over data representing a second sound source the person is not facing. At least one speaker utilizes the data to reproduce sounds to the person. An active noise reduction system provides a signal to the speaker for reducing an amount of ambient acoustic noise in the vicinity of the person that is heard by the person.Type: GrantFiled: November 20, 2013Date of Patent: March 7, 2017Assignee: Bose CorporationInventors: William R. Short, Luke C. Walters

Patent number: 9078077Abstract: An approach to forming output signals both permits flexible and temporally and/or frequency local processing of input signals while limiting or mitigating artifacts in such output signals. Generally, the approach involves first synthesizing prototype signals for the output signals, or equivalently characterizing such prototypes, for example, according to their statistical characteristics, and then forming the output signals as estimates of the prototype signals, for example, as weighted combinations of the input signals.Type: GrantFiled: October 21, 2011Date of Patent: July 7, 2015Assignee: Bose CorporationInventors: Paul B. Hultz, Tobe Barksdale, Michael Dublin, Luke C. Walters

Patent number: 8620650Abstract: A system for combining signals includes a first microphone generating a first input signal having a first voice component and a first noise component, a second microphone generating a second input signal having a second voice component and a second noise component, a mixing circuit, and an adaptive filter. The mixing circuit applies a first gain having a value ? to the first input signal to produce a first scaled signal, applies a second gain having a value 1?? to the second input signal to produce a second scaled signal, and sums the first scaled signal and the second scaled signal to produce a summed signal. The adaptive filter computes an updated value of ? to minimize the energy of the summed signal based on the summed signal, the first input signal and the second input signal, and provides the updated value of ? to the mixing circuit.Type: GrantFiled: April 1, 2011Date of Patent: December 31, 2013Assignee: Bose CorporationInventors: Luke C. Walters, Vasu Iyengar, Martin David Ring
