In a method for producing a directional microphone characteristic and hearing aid device having a directional microphone characteristic, high-pass filters following two omnidirectional microphones are matched as to their limit frequencies for amplitude response and/or phase response of the two microphones. The limit frequency of the high-pass filter following one microphone is matched to the limit frequency of the other microphone.
