Patent number: 11632632Abstract: Presented herein are techniques for adapting settings/operations of a remote microphone device associated with an auditory prosthesis based on a desired/preferred listening direction of a recipient of the auditory prosthesis. More specifically, an auditory prosthesis worn by a recipient and a remote microphone device, which are configured to wirelessly communicate with one another, are both positioned in the same spatial area. At least one of a recipient-specified (e.g., recipient-preferred) region of interest within the spatial area, or a recipient-specified listening direction, is determined. Based on a determined relative positioning (e.g., location and orientation) of the remote microphone device and the auditory prosthesis, operation of the remote microphone device is dynamically adapted so that the remote microphone device can focus on (e.g., have increased sensitivity to) sounds originating from the recipient-specified region of interest/listening direction.Type: GrantFiled: May 12, 2021Date of Patent: April 18, 2023Assignee: Cochlear LimitedInventors: Jan Patrick Frieding, Soren Nilsson, Kenneth Oplinger, Alexander von Brasch, Roger Smith, Richard Murphy
