Abstract:
The interference powers with directional microphones are to be suppressed as far as possible. To this end, provision is made to adaptively filter the microphone of a number of microphones as a function of at least one parameter. The directional effect of the directional microphone achieved in this way is adjusted by modifying the at least one parameter, such that the summation of interference powers including microphone noises is reduced and/or minimal.
