Abstract

With a hearing aid device having a device element which can be worn on or behind the ear and an earmold which protrudes at least partially into the auditory canal of a user, in which earmold a receiver is arranged, the protection of the receiver from contamination is to be improved. To this end, a sound outlet opening in the earmold is covered with a membrane and a ventilation channel is provided for the rear ventilation of the membrane, with at least one segment of the ventilation channel running in a connecting piece, which connects the device element to the earmold.
