Abstract
The protection of the ports of a hearing device, in particular microphone ports, is to be more easily operable in terms of installation and replacement. Provision is made for this purpose for protection to be provided by an adhesive film with a plastic membrane, which is essentially acoustically permeable, and an adhesive layer, which is attached to the plastic membrane. The adhesive is cut out in a predetermined shape at least one specified location on the plastic membrane. It is thus possible to affix an easily operable common microphone protection system to the hearing device shell, for example for a directional microphone with several microphone ports.
