Abstract: Presented herein are techniques for wirelessly communicating sound data and one or more sound signal attributes from an external component of a medical device to an implantable component of the medical device via one or more data packets. For example, when the medical device is embodied as a hearing device, such as a cochlear implant system or hearing aid, sensory data and one or more sensory signal attributes determined from input sensory data can be combined into data packets by an external component and wirelessly transmitted to an implantable component of the cochlear implant system. The cochlear implant can separate the sensory data and one or more sensory signal attributes from the data packets and further process the sensory data using the one or more sensory signal attributes in order to generate stimulation signals for delivery to a recipient of the cochlear implant system.

Abstract: Disclosed embodiments include systems and methods of configuring, e.g., a hearing prosthesis comprising a beamforming microphone array having two or more microphones. Some embodiments include (i) storing a plurality of sets of beamformer coefficients in memory, where each set of beamformer coefficients corresponds to one of a plurality of zones on a recipient's head, and (ii) configuring the hearing prosthesis with a set of beamformer coefficients that corresponds to the zone on the recipient's head where the beamforming microphone array is located. Other embodiments include determining a set of beamformer coefficients based on magnitude and phase differences between microphones of the beamforming array, where the magnitude and phase differences are determined from a plurality of head related transfer function measurements for the microphones.

Abstract: Techniques for addressing impulse sounds in an auditory prosthesis. The auditory prosthesis comprises a sound processor that is configured to convert received sound signals into output signals for use in generating stimulation for delivery to a recipient of the auditory prosthesis. The sound processor comprises an impulse-aware gain system that is configured to generate a time-variable gain for the application to the audio signal. The time-variable gain applied to the audio signal is dependent on both a level of the audio signal and the presence or absence of impulse sounds in the audio signal.

Abstract: Presented herein are techniques for providing tinnitus relief to recipients of a hearing prosthesis. In accordance with embodiments presented herein, a hearing prosthesis comprises a tinnitus relief system that is configured to generate a tinnitus masker signal that comprises a plurality of discrete (separate) components. The tinnitus relief system is configured to inject the components of the tinnitus masker signal directly into a sound processing path so that the masker components are combined with different processed portions of a channelized sound signal. The channelized sound signal and the components of the tinnitus masker signal are used to generate one or more output signals for use in compensation of a hearing loss of a recipient of the hearing prosthesis.

Abstract: A computer-implemented method comprising: determining one or more features of a subject signal; revising one or more control signals on the basis of the one or more features; modifying a level of the subject signals based on the control signals. At least one of the features is determined by: comparing a given one of the subject signals against a boundary signal to produce a corresponding given boundary comparison signal; and summarizing the behavior of the given boundary comparison signal over a time interval.
