Abstract (en)
The invention relates to an array microphone (30), which is formed from at least two basic microphones connected with a signal processor, which makes use of an algorithm for the processing of the signals of the basic microphones. The array microphone is characterized in that the basic microphones are sound field microphones (5, 5').
