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.

Abstract: A method comprises deriving a control signal (3) from an input signal (1). The process of deriving the control signal comprises a standard processing (6) so as to provide a standard processed control signal component (7) based on a standard compressor characteristic, and an individualized processing (10) so as to provide an individualized processed control signal component (11) based on an individualized compressor characteristic. The standard and individualized processed control signal components are multiplied together to form the control signal. The invention further provides a hearing aid.
