ABSTRACT:
In a hearing device with low feedback tendency with simultaneous open feed and utilization of the natural directional effect of the pinna, the hearing device has a tube-shaped ear fitting piece for insertion into an auditory canal and speaker is arranged in the ear fitting piece, and at least two microphones are arranged in the ear fitting piece acoustically-symmetrically to the speaker in the built-in state of the hearing device in the ear fitting piece. The sound emitted by the speaker that can be differentiated from the usable sound, such that the level of feedback can be reduced. At the same time, open feed and utilization of the natural directional effect of the pinna are ensured.
