In a method and a device for the signal processing in a hearing aid, in which coefficients of a filter for the frequency-dependent amplitude adaptation of an input signal are adapted in accordance with this input signal, the following steps are carried out: Determining coefficients of a compression amplification g<SUB>m</SUB>, which describe a frequency-dependent adaptation of the input signal in accordance with frequency-dependent signal levels of the input signal, determining coefficients of a noise suppression a<SUB>m</SUB>, which describe a frequency-dependent adaptation of the input signal in accordance with interference noises detected in the input signal, and the calculation of the coefficients of the filter ( 6 ) c<SUB>m </SUB>out of the coefficients of the compression amplification g<SUB>m </SUB>and the coefficients a<SUB>m </SUB>of the noise suppression. In this, only a single controllable filter is utilised both for the compression amplification as well as for the noise suppression, and a delay time for the filtering of the input signal is kept short.
