Abstract
The cleaning and exchange of components of the hearing aid which is necessary at regular intervals due to the conventional contamination is uncomfortable and expensive. The housing (G) and any protective devices (K) which are to protect from contamination, are provided with a dirt-resistant layer. In this way, the dirt adheres less strongly to the hearing aid, so that if necessary it can be removed by means of tapping.
