摘要： 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.

摘要： Exemplary systems and methods for optimizing a compliance voltage of an auditory prosthesis are disclosed. Each stimulation channel formed by electrodes that are coupled to an auditory prosthesis may have an adjustable current steering range associated therewith. Each adjustable current steering range is centered about the midpoint of its respective stimulation channel and defines a range of current steering that may be used within its respective stimulation channel. A compliance voltage of an auditory prosthesis may be optimized by setting a current steering range for one or more stimulation channels to a value that results in an optimum balance between power conservation and performance of the auditory prosthesis.
