1. A method of operating a hearing aid system comprising the steps of:

  • providing an input signal representing an acoustical signal from an input transducer of the hearing aid system;

    providing the input signal to an auditory nerve compressor;

    selecting a minimum output level for the auditory nerve compressor, wherein the minimum output level represents a hearing threshold level;

    selecting a maximum output level for the auditory nerve compressor;

    from a range between 30 and 50 dB SL if an auditory neurodegeneration has been identified for both medium-spontaneous rate and low-spontaneous rate auditory nerve fibers;

    orfrom a range between 50 and 80 dB SL if an auditory neurodegeneration has been identified only for low-spontaneous rate auditory nerve fibers,defining a minimum input signal level and a maximum input signal level;

    operating the auditory nerve compressor according to a compression characteristic wherein the minimum input signal level is mapped onto the minimum output level of the auditory nerve compressor, and wherein the maximum input signal level is mapped onto the maximum output level of the auditory nerve compressor; and

    using an output signal derived from the auditory nerve compressor output signal to drive an electrical-acoustical output transducer of the hearing aid system.
