Abstract (en)
[origin: EP0836364A2] A hearing aid with a microphone, an amplifier arrangement connected to the microphone and a sound generator energized by the amplifier and having an output connected to a sound guide structure (10, 10', 10'') which is directed toward an ear, or respectively, an eardrum of a user, wherein between the auditory canal (6) and the sound guide structure (10' ,10', 10''), a gap remains permitting passage of ambient sounds. In order to prevent fringe haul-generating feedback coupling in spite of the small and compact dimensions of the hearing aid, the sound guide structure (10, 10' 10'') includes a plurality of air containing channels of different lengths having staggered sound discharge openings. <IMAGE>
