Abstract
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.
