Patent number: 11979715Abstract: Presented herein are techniques for enhancing a hearing prosthesis recipient's perception of multiple frequencies present in received sound signals. The hearing prosthesis is configured to extract a plurality of frequencies from the received sound signals and to use the plurality of frequencies to modulate the amplitudes of different stimulation pulse sequences that are to be delivered to the recipient via different stimulation channels. The hearing prosthesis may also adapt a stimulation resolution of the stimulation pulse sequences when delivering the modulated stimulation pulses sequences to the recipient.Type: GrantFiled: October 19, 2022Date of Patent: May 7, 2024Assignee: Cochlear LimitedInventors: Naomi Croghan, Harish Krishnamoorthi, Zachary Mark Smith

Publication number: 20230338733Abstract: Presented herein are techniques to calculate long-term loudness measures for each of the prostheses in a bimodal hearing system and exchange this information across the two sides. The bimodal hearing system operates to ensure that the loudness differences between the two sides follow the ILDs between the two sides. Stated differently, the techniques presented herein determine a target loudness ratio based on the input signals (sound signals) received at each of the first second hearing prostheses in a bimodal hearing system. The techniques presented herein further determine an estimated inter-aural loudness ratio based on output signals that would be generated by each of the first and second hearing prostheses based on the input signals. Operation of either or both of the first or second hearing prostheses is adjusted so as to substantially match the estimated inter-aural loudness ratio to the target loudness ratio.Type: ApplicationFiled: June 7, 2021Publication date: October 26, 2023Inventor: Harish KRISHNAMOORTHI

Patent number: 10237664Abstract: Disclosed herein are methods, systems, and devices for discontinuously recording audio input representative of an audio environment. The audio environment can be an environment of a recipient of a hearing prosthesis and the discontinuously recorded audio input can be used to characterize the audio environment of the recipient, to control settings of the hearing prosthesis, or to provide some other application. Discontinuously recording the audio input can provide a recording that characterizes the audio environment of the recipient while protecting the privacy of individuals speaking nearby the recipient. Discontinuously recording the audio input may include recording discontinuous time segments of the audio input such that the semantic content of speech within the audio input, the identity of speakers in the audio input, or other private information present in the audio input is masked.Type: GrantFiled: May 19, 2016Date of Patent: March 19, 2019Assignee: Cochlear LimitedInventors: Zachary Mark Smith, Harish Krishnamoorthi

Patent number: 9055374Abstract: A method and apparatus for determining an auditory pattern associated with an audio segment. An average intensity at each of a first plurality of detector locations on an auditory scale based at least in part on a first plurality of frequency components that describe a signal is determined. A plurality of tonal bands in the audio segment, wherein each tonal band comprises a particular range of detector locations of the first plurality of detector locations is determined. Corresponding strongest frequency components in the tonal bands are determined. A plurality of non-tonal bands is determined, and each non-tonal band is subdivided into multiple sub-bands. Corresponding combined frequency components that are representative of a combined sum of intensities of the first plurality of frequency components that is in a corresponding sub-band are determined. An auditory based on the corresponding strongest frequency components and the corresponding combined frequency components is determined.Type: GrantFiled: June 24, 2010Date of Patent: June 9, 2015Assignee: Arizona Board of Regents for and on behalf of Arizona State UniversityInventors: Harish Krishnamoorthi, Andreas Spanias, Visar Berisha
