Abstract: An exemplary cochlear implant system includes a cochlear implant and a processing unit communicatively coupled with the cochlear implant. The cochlear implant may include a first optical element implanted within a recipient and positioned toward an inner surface of a skin flap of the recipient. The processing unit may cause an optical signal transmission between the first optical element and a second optical element included in an external device positioned toward outer surface of the skin flap relative to the first optical element. The optical signal transmission may include a transmission of an optical signal through the skin flap between the inner surface and the outer surface of the skin flap. Based on the optical signal transmission, one or more properties associated with the skin flap of the recipient may be determined.

Abstract: An exemplary system is configured to maintain data representative a machine learning model for use in a cochlear implant system and train the machine learning model. The training may include applying audio content as a training input to the machine learning model, the machine learning model configured to apply a machine learning heuristic to the audio content to output an electrical signal representative of the audio content; applying the electrical signal to a brain processing model, the brain processing model configured to output synthesized audio content representative of the electrical signal; generating an error metric representative of a difference between the audio content and the synthesized audio content; and feeding back the error metric into the machine learning model, the machine learning model configured to use the error metric to adjust the machine learning heuristic applied to the audio content.

Abstract: An exemplary system comprises a first and second hearing device associated with a first and second ear of a user, respectively. The first hearing device is configured to detect a first audio signal representative of audio content, generate a first intermediate signal representation (ISR) corresponding to the first audio signal, the first ISR comprising a sparsely-encoded non-audio signal having a complexity measure that is below a threshold, and transmit the first ISR to the second hearing device. The second hearing device is configured to detect a second audio signal representative of the audio content, generate a second ISR corresponding to the second audio signal, and transmit the second ISR to the first hearing device. The first hearing device is further configured to generate, based on the first and second ISRs, an output audio signal, and provide the output audio signal to the first ear of the user.
