    摘要： A signal processing arrangement generates electrical stimulation signals to electrode contacts in an implanted cochlear implant array. An input sound signal is analyzed to determine characteristic frequency components. One or more stimulation events are requested based on the timing and amplitude of the frequency component. A frequency-specific stimulation sequence (FSSS) is generated for stimulation of a plurality of adjacent electrode contacts. The FSSS starts with a stimulation pulse to the highest-frequency, most-basal electrode contact of the adjacent electrode contacts, ends with a stimulation pulse to the lowest-frequency, most-apical electrode contact of the adjacent electrode contacts, and reaches a maximum stimulation amplitude at a frequency-specific location within the cochlea corresponding to a natural traveling wave maximum. The electrode stimulation signals are then generated from the FSSS for delivery by the electrode contacts to adjacent auditory neural tissue.

    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： The application relates to a hearing device comprising an ITE-part adapted for being located at or in an ear canal of a user, a configurable signal processing unit for processing an input signal, and a feedback estimation unit for providing a current estimate of an acoustic feedback path from an output transducer to an input transducer, a memory for storing frequency dependent reference estimates of the acoustic feedback path the real ear to coupler difference, when the ITE-part is correctly mounted, an optional probe signal generator for generating a probe signal at least in a specific measurement mode, wherein the hearing device is configured to perform measurement of the current estimate of the acoustic feedback path. The hearing device further comprises a control unit operatively connected to said memory and to said signal processing unit, and configured to compare said current estimate of the acoustic feedback path with said reference estimate of the acoustic feedback path, and to provide a current feedback path difference measure, and to determine a current estimate of real ear to coupler difference from the current feedback path difference measure. This has the advantage facilitating the mounting of the ear ITE-part. The invention may e.g. be used in hearing aids for compensating a user's hearing impairment.
