摘要： A method and a system for measuring a main electrically evoked compound action potential is described. The system may comprise a cochlea implant system which includes an electrode array, and where the electrode array includes at least a stimulator electrode, a first recording electrode and a second recording electrode, and where the first recording electrode is arranged closer to the stimulator electrode than the second recording electrode, a processor electrically in communication with the cochlea implant system. The processor may be configured to apply a stimulation including a first primary stimulation paradigm to the stimulator electrode and to receive a first primary cochlea response signal recorded by the first recording electrode while applying the stimulation, and to receive a first secondary cochlea response signal recorded by the second recording electrode, and determine the main electrically evoked compound action potential based on a difference between the first primary cochlea response signal and the first secondary cochlea response signal.

摘要： A signal processor for a hearing device with an implantable stimulator having two or more electrodes for emitting electric charge pulses to neural-fibers of an individual. The processor has a signal path comprising an input circuit adapted to receive an acoustic-signal from the surroundings and provide at least one corresponding input audio-signal; a filter bank adapted to provide at least one band-limited audio-signal in dependence on the at least one input audio-signal; and a noise filter adapted to attenuate undesired signal components in the at least one band-limited audio-signal and to provide at least one corresponding noise-filtered signal. The processor is characterised in that the portion of the signal path preceding the noise filter neither causes an effective level compression nor an effective level expansion of the at least one noise-filtered signal when the at least one noise-filtered signal is derived from an acoustic signal having a level within the comfortable acoustic range.
