With a hearing aid device barometric pressure equalization is intended to be achieved in a simple and economical manner in a sound canal between an earpiece and a cerumen protection system with a gas-tight membrane. To this end a pressure equalization canal is proposed, which opens into the sound canal. The pressure equalization canal preferably connects the sound canal to a vent. It can be produced in a simple manner when manufacturing the housing of the hearing aid device using a computer-aided manufacturing method.

In-the ear hearing aid device with a vent

A hearing device has an ear fitting piece, a housing part wearable behind the ear, and an earpiece tube connecting the ear fitting piece and the housing part. The transmission of mechanical vibrations between the ear fitting piece and the housing part via the earpiece tube is prevented by damping elements located in the region of the connection points between the ear fitting piece and the earpiece tube, or between the earpiece tube and the housing part. The damping elements damp mechanical vibrations in the transition region. A damping element that prevents the transmission of mechanical vibrations can also be present on or in the earpiece tube. The feedback tendency in the appertaining hearing device is thereby reduced.

Hearing device with a damping element

The increasing miniaturization of hearing aids means that less and less space is available for accommodating controls (). It is thus proposed that, at least one proximity sensor (A,B) be provided on a hearing aid () so as to enable an operating function to be performed even without touching a control directly. For operation of a hearing aid () in accordance with the invention, in addition to the hearing aid () itself, no further technical aids such as remote control, magnets etc. have to be worn as well.
