The housing has a face adapted for abutment on the tragus, a face adapted for abutment on the antitragus, a mouthpiece adapted for being inserted into the mouthing of the auditory tract. A resilient means is adapted to abutment on the cartilage arch between the antihelix and the concha and influences the housing by a force oriented forwards towards the tragus. The resilient means is a leaf spring with a spring rigidity that decreases with the distance from the housing, whereby a uniform distribution of the force towards the cartilage arch at the concha is provided. The device may be a passive noise shield or it may have on eor two transducers for one-way or two way communication.
