57 Zusammenfassung AB [EN] It is intended to improve and automate the calculation of calibration filters connected downstream from the microphones of an RGSC beamformer. To this end it is proposed that an adaptive calibration filter calculation unit be used, by means of which calibration filters are calculated from the output signals of adaptive blocking filters such that the power of an output signal of a blocking filter subtracted from a reference signal and filtered by means of a calibration filter respectively is minimized. The calibration filters connected downstream from the microphones are then replaced by the calibration filters thus determined.
