Abstract

Hearing aid with at least two microphones with sound inlets disposed at a distance from one another as a recording device. Through optional activation of a single or at least two parallel-connected microphones, a change in the recording characteristic, for example from omnidirectional to directional, is achieved. This change can be performed by the user himself by means of an electronic switchover. <IMAGE>
