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.

Systems and methods for monitoring and acting on a physiological condition of a stimulation system recipient

A binaural hearing system includes a binaural pair of microphones that are configured to be located, respectively, at a first ear and a second ear of a user. The system further includes an interconnected binaural pair of sound processors that are associated with the binaural pair of microphones. The sound processors are configured to preserve an interaural level difference ('ILD') between a first signal generated by the first microphone and a second signal generated by the second microphone. The sound processors do this by performing a contralateral gain synchronization operation to a first degree with respect to the first and second signals at the first sound processor, and to a second degree with respect to the first and second signals at the second sound processor, where the first degree is distinct from the second degree or at least one of the first and second degrees is a partial degree.

Binaural hearing systems and methods for preserving an interaural level difference between signals generated for each ear of a user

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.

Systems and methods for facilitating interaural level difference perception by enhancing the interaural level difference

A binaural hearing system ('system') preserves and/or enhances interaural level differences ('ILDs') between first and second signals. The system includes audio detectors each associated with an ear of a user. 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 each ear. The system also includes sound processors associated with each ear that each receive the first and second signals from the audio detectors directly and/or by way of a communication link from the other sound processor. The sound processors each perform operations with respect to the first and second signals to preserve and/or enhance the ILDs between the signals. In so doing, the sound processors perform a contralateral gain synchronization operation to a first degree at the first sound processor and to a distinct second degree at the second sound processor.
