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 characterized 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.
