H04R 25/00

Abstract:

An illustrative cochlear implant system includes an electrode lead having an array of electrodes, a cochlear implant coupled with the electrode lead and configured to be implanted within a recipient together with the electrode lead, and a processing unit communicatively coupled to the cochlear implant. The processing unit is configured to direct the cochlear implant to apply stimulation to the recipient by way of the array of electrodes. The processing unit is further configured to detect, by way of one or more electrodes included in the array of electrodes, a cortical potential produced by the recipient. Based on the detected cortical potential, the processing unit is configured to determine a fitting parameter associated with the cochlear implant system. Corresponding systems and methods are also disclosed.

Abstract:

An illustrative system includes a stimulation device configured to apply stimulation to a recipient, a sensing device configured to detect a physiological condition of the recipient, and a processing unit communicatively coupled to the stimulation device and the sensing device. The processing unit determines a stimulation strategy that is customized to the recipient and includes stimulation frames and stimulation gaps. The processing unit then directs the stimulation device to apply the stimulation to the recipient in accordance with the stimulation strategy by applying the stimulation only during time that corresponds to the stimulation frames. The processing unit also directs the sensing device to detect the physiological condition of the recipient in accordance with the stimulation strategy by detecting only during time that corresponds to the stimulation gaps. Based on the detected physiological condition, the processing unit performs an action. Corresponding systems, methods, and apparatuses are also disclosed.

International Classification:

H04R 25/00

Abstract:

A binaural hearing system (“system”) enhances and/or preserves interaural level differences between first and second signals. The system includes first and second audio detectors associated with first and second ears of a user, respectively. The audio detectors detect an audio signal presented to the user and generate the first and second signals to represent the audio signal as detected at the first and second ears, respectively. The system also includes a first sound processor that receives the first signal from the first audio detector and the second signal from a second sound processor via a communication link with the second sound processor. The first sound processor generates a directional signal representative of a spatial filtering of the audio signal detected at the first ear according to an end-fire directional polar pattern and presents an output signal representative of the directional signal to the user at the first ear.
