To improve the signal transmission behavior in a hearing aid with a directional microphone system having at least three microphones, a number of those microphones are connected to form microphone units, the order of the directional characteristic of these microphone units being matched in each case. The microphone signals of these microphone units are added so that the order of the directional characteristic of the resulting microphone system also corresponds to the order of the directional characteristic of the individual microphone units. As a result, the signal transmission behavior is improved in comparison to an individual microphone unit, without causing increased microphone noise or worsening of the sound quality.
