Abstract
With a hearing aid device which can be worn in the ear, a barometric pressure equalization which is needed for the sound transducer, such as a microphone or receiver, is to be achieved in a simple and cost-effective fashion. To this end, a converter protection facility is proposed with a membrane, with a pressure equalization channel, which connects a sound channel to the interior of the hearing aid device, extends through the transducer protection facility at least in one section. Replacing the transducer protection facility thus also replaces this subsection of the pressure equalization channel. A possible blockage of the pressure equalization channel which exists in this region as a result of dirt or moisture is eliminated as a result.
