Abstract
A direction-sensitive hearing aid is provided with a housing, at least one signal processor, at least one microphone in communication with the signal processor as well as at least one sound opening. A simplified arrangement of operating elements is provided as well as effective shielding from electromagnetic disturbances with a continued, good directional effect given improved protection against contamination. The hearing aid is provided with a sound channel. The sound channel has at least two openings, and at least two microphones are positioned along the sound channel via which the sound within the sound channel can be acquired. The direction of the sound can be determined based on the differences in sound transit time within the sound channel.
