摘要：
In a method and a system non-uniformities of a plurality of microphones (301) are compensated for by adaptively filtering (350) the microphone signals on the basis of a reference signal that is derived from the microphone signals. In this way, the filter coefficients are updated so as to respond to varying environmental conditions and/or changes in the microphone characteristics.
