摘要： An electric acoustic stimulation (EAS) hearing system includes a signal processor for processing an acoustic signal input to generate: i. an electrical communications signal representative of an upper electrical range of acoustic frequencies, and ii. an acoustic communications signal representative of a lower acoustic range of acoustic frequencies, the acoustic range including: (1) a lower subrange of acoustic frequencies perceivable by the patient with amplification, and (2) an upper subrange of acoustic frequencies not perceivable by the patient, wherein the signal processor uses frequency transposition to include the upper subrange in the lower subrange. An implanted electrical stimulation subsystem receives the electrical communications signal and delivers a corresponding electrical stimulation signal to auditory neural tissue of an implanted patient. An external acoustic stimulation subsystem receives the acoustic communications signal and delivers a corresponding amplified acoustic stimulation signal to the ear canal of the patient.

摘要： Approaches are described for adjusting a cochlear implant system that has an electrode array with multiple electrode contacts, which is implanted in a patient. For selected individual electrode contacts, a corresponding channel-specific monoaural interaction component (MIC) score is calculated that represents a channel interaction factor based on a ratio of: i. an electrically evoked auditory brain-stem response (cABR) measurement of an electrical stimulation signal applied to the individual electrode contact, and ii. a sum of individual eABR measurements from simultaneous electrical stimulation of selected electrode contacts nearest to the individual electrode contact. Each electrode contact having a channel-specific MIC score below a MIC score threshold value is then deactivated, whereby electrical stimulation signals are not delivered to deactivated electrode contacts.

摘要： A hearing signal processor processes an input sound signal and generates an electrical communications signal for an upper range of sound frequencies, and an acoustic communications signal for a lower range of sound frequencies. An implanted electrical stimulation subsystem includes an electrode array with one or more electrode contacts in an acoustically perceivable cochlear region retaining residual natural hearing. The electrical stimulation subsystem receives the electrical communications signal and delivers corresponding electrical stimulation signals to the electrode contacts for electrical stimulation of adjacent neural tissue. An external acoustic stimulation subsystem receives the acoustic communications signal and delivers corresponding amplified acoustic stimulation signals to the ear canal of the patient. The upper range and the lower range overlap and the electrical stimulation signals and the amplified acoustic stimulation signals are coordinated for simultaneous delivery to the acoustically perceivable cochlear region.

摘要： A method of measuring electrically evoked auditory brainstem responses of a patient or animal body is provided. The method includes surgically implanting an auditory prosthesis having an electrode array, the electrode array positioned either intracochlear or substantially proximate a brainstem of the body. At least one electrode is stimulated in the electrode array. Electrically evoked auditory brainstem responses resulting from said stimulation are recorded using, at least in part, an electrode in the electrode array as a negative electrode, and a positive electrode positioned substantially proximate the vertex of the head of the body.
