A method of eliminating interference components in a microphone signal by generating
a compensation signal and subtracting the compensation signal from the microphone
signal. The compensation occurs completely in the frequency domain and the output
signal is processed in the frequency domain as well. Measures for reducing the
expenditure during the signal processing are specified. For example, advantageous
modifications provide that a filter setting, obtained during a preceding speech
pause, be used for eliminating interference in a voice signal and/or that the simulation
filter be divided into several partial filters for long pulse responses. In particular,
the invention is suitable for eliminating interference signal components, e.g.,
caused by a radio or the like, from a voice input signal in a motor vehicle, the
source signal of which is available as reference signal.
