Abstract: A method (400) of operating an ear level audio system, comprises the steps of applying (401) a first frequency dependent gain to an input signal in order to provide a first processed input signal adapted to at least one of compensating a hearing loss and suppressing noise, determining (402) a noise floor level of the first processed input signal, applying (403) a second frequency dependent gain to the first processed input signal and hereby providing an output signal such that for at least one frequency range the noise floor level of the output signal is positioned at a selected position above or below a hearing threshold.

Abstract: A method of noise reduction of low-level input signals in a hearing aid involves applying compression to the input signal using a first compression ratio if a detected measure of amplitude modulation in the input signal is below a selected modulation level, and using a second compression ratio if the measure of amplitude modulation is above the selected modulation level. This reduces the volume of low-level steady-state noise while increasing the volume of modulated signals, e.g. speech. A hearing aid having a noise reduction system (10) has means for determining a level of amplitude modulation from a noise level and an absolute average level of an input signal, and comprises a dynamic compressor having a first compression ratio and a second compression ratio. The means for determining the level of amplitude modulation is configured to control the dynamic compressor in such a way that, below a predetermined input level, unmodulated sounds are amplified less than unmodulated sounds. In this way, low-level, unmodulated sounds are dampened by the hearing aid.
