Abstract
A method performs frequency-dependent reduction of noise in an input signal, wherein the input signal is allocated to a main signal path and to an auxiliary signal path. A filter bank separates the input signal into a plurality of frequency bands each having a certain bandwidth and center frequency. In the auxiliary signal path, the bandwidth of the signal component is reduced in each frequency band thus forming a reduced frequency band in each case. Wherein in each reduced frequency band, a reduction parameter is determined from the signal component of the input signal, and wherein in the main signal path in each frequency band, noise in the input signal is reduced by use of the reduction parameter in that frequency band.
