Zusammenfassung: | The hearing device comprises at least one microphone arranged within the housing of the hearing device, with its sound inlet aperture (′) being connected via a canal to the outside of the housing and a sound permeable cover serving as microphone protection that is arranged in the region of the outlet opening of said canal. The canal of the hearing device is provided as a blind hole and the microphone is arranged at the side of said canal and at least one opening or channel is provided connecting said canal with said sound inlet aperture (′) of said microphone. By providing the canal as a blind hole, all dirt eventually intruding the canal will be collected at the bottom (″) of canal and will therefore not reach directly the microphone or the sound inlet openings of the microphone respectively. |
