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： A binaural cochlear implant system (system) includes first and second microphones associated with first and second ears of a patient, respectively. The microphones detect an audio signal presented to the patient and output first and second signals representative of 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 microphone and the second signal from a second sound processor by way of a communiation link with the second sound processors. The first sound processor generates first and second fine structure signals representative of fine structure information of the first and second fine structure signals, respectively, and generates a timing pulse signal based on the first and second fine structure signals. The first sound processor uses the timing pulse signal to represent to the patient an interaural time difference between the first and second signals.

摘要： Errors in pitch allocation within a cochlear implant are corrected in order to provide a significant and profound improvement in the quality of sound perceived by the cochlear implant user. The disclosure provides a tool for determining the implant fitting curve for cochlear implant system to correct pitch warping. The method presents familiar musical tunes to determine the implant fitting slope (relative alignment). In addition, in one embodiment, speech sounds may be used to determine the offset of the fitting line (absolute alignment). The use of music and speech to determine the implant fitting curve (line) and the slope is facilitated by using techniques to implement virtual electrodes to more precisely direct stimuli to the location or “place” on the cochlea.
