Abstract: Diagnosing and treating presbycusis (age related hearing loss) includes measuring basilar membrane stiffness. In an example, a low frequency component of an electrocochleogram stimulation signal is used to bias a region of the basilar membrane, the results of which are used basilar membrane stiffness. The resulting measurement is used to measure a subcomponent of presbycusis. Further, the measurement can be combined with known diagnostic methods to reveal or distinguish other origins of hearing loss such as strial presbycusis, sensory presbycusis, neural presbycusis, and cochlea conductive presbycusis. The relative contributions for each of the diagnosed origins of hearing loss can be determined.

Abstract: 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.

Abstract: An auditory prosthesis comprising an actuator for providing mechanical stimulation to a recipient. The auditory prosthesis comprises a measurement circuit for use in determining the resonance peak(s) of the actuator. In an embodiment, the measurement circuit measures the voltage drop across the actuator and/or current through the actuator during a frequency sweep of the operational frequencies of the actuator. These measured voltages and/or currents are then analyzed for discontinuities that are indicative of a resonance peak of the actuator. In another embodiment, rather than using a frequency sweep to measure voltages and/or currents across the actuator, the measurement circuit instead applies a voltage impulse to the actuator and then measure the voltage and/or current across the actuator for a period of time after application of the impulse. The measured voltages and/or currents are then analyzed to identify resonance peak(s) of the actuator.

Abstract: Treatment actions can be taken based on an analysis of the ability of a recipient of an auditory prosthesis to perceive musical activities. The occurrence of musical activities and the recipient's response thereto can be determined based on transducers. The recipient's musical perception can be determined by analyzing the signals from the transducers as stand-alone measures or by comparing the signals against known music. The treatment actions can relate to the treatment of a hearing-impairment of the recipient of the auditory prosthesis, such as by modifying the settings of the auditory prosthesis to affect the ongoing operation of the auditory prosthesis.

Abstract: A method and system to help determine the extent to which a hearing prosthesis recipient is exposed to speech. The hearing prosthesis will log data regarding audio input, optimally in correspondence with times when the hearing prosthesis is in a stimulation-on mode in which the hearing prosthesis is set to stimulate a physiological system of the recipient in accordance with received audio input, so as to facilitate identification of speech to which the recipient is exposed. Further, as the hearing prosthesis itself receives the audio input, the hearing prosthesis may analyze the audio input to determine one or more linguistic characteristics of the audio input, such as a quantity of speech by the recipient and/or by others, and the hearing prosthesis may output data representing the determined one or more linguistic characteristics. Advantageously, the data may then be used to help facilitate rehabilitation of the recipient.
