A method for processing and controlling sound signals in a hearing aid is provided. The method comprises estimating a first and a second signal level of an electric input signal based on a first and a second signal level estimator adapted for responding according to a first and a second speed respectively, where the second speed is lower than the first speed and where the estimated second signal level is subtracted from the estimated first signal level, thereby forming a third signal level. Subsequently a first and a second compressor gain control output are determined in a first and second compressor based on said third and second signal level respectively. Then the first and second compressor gain control outputs are summed and hereby a net gain control signal is created. Finally the electric input signal is amplified in accordance with the net gain control signal and thereby creating an electric output signal. The invention also relates to a hearing aid operating according to said method.
