Patent number: 10425745Abstract: A hearing assistance system obtains a first input audio signal that is based on sound received by a first set of microphones. The system also obtains a second input audio signal that is based on sound received by a second, different set of microphones. A first adaptive beamformer generates a first output audio signal based on the first input audio signal, the second input audio signal, and a value of a first parameter. A second adaptive beamformer generates a second output audio signal based on the first input audio signal, the second input audio signal, and a value of a second parameter. The value of the first parameter and the value of the second parameter are determined such that a magnitude squared coherence (MSC) of the first output audio signal and the second output audio signal is less than or equal to the coherence threshold.Type: GrantFiled: May 17, 2018Date of Patent: September 24, 2019Assignee: Starkey Laboratories, Inc.Inventors: Ivo Merks, John Ellison, Jinjun Xiao

Patent number: 10034102Abstract: Disclosed herein, among other things, are apparatus and methods for annoyance perception and modeling for hearing-impaired listeners. One aspect of the present subject matter includes a method for improving noise cancellation for a wearer of a hearing assistance device having an adaptive filter. In various embodiments, the method includes calculating an annoyance measure or other perceptual measure based on a residual signal in an ear of the wearer, the wearer's hearing loss, and the wearer's preference. A spectral weighting function is estimated based on a ratio of the annoyance measure or other perceptual measure and spectral energy. The spectral weighting function is incorporated into a cost function for an update of the adaptive filter. The method includes minimizing the annoyance or other perceptual measure based cost function to achieve perceptually motivated adaptive noise cancellation, in various embodiments.Type: GrantFiled: November 23, 2015Date of Patent: July 24, 2018Assignee: Starkey Laboratories, Inc.Inventors: Tao Zhang, Martin McKinney, Jinjun Xiao, Srikanth Vishnubhotla, Buye Xu

Patent number: 9875754Abstract: An audio system processes a speech signal to maintain a target value of the speech intelligibility index (SII) while minimizing the overall speech level so that speech intelligibility is preserved across different environmental sound levels while possible distortions and overall loudness are mitigated. In one embodiment, a hearing aid processes a speech signal received from another device to maintain a target value of the SII while minimizing the overall speech level before mixing the speech signal with a microphone signal.Type: GrantFiled: May 8, 2014Date of Patent: January 23, 2018Assignee: Starkey Laboratories, Inc.Inventors: William S. Woods, Tarun Pruthi, Jinjun Xiao
