Abstract

The present invention provides the ability to efficiently detect a defect of an earwax protection device membrane. To achieve this, a high contrast is set between the membrane and the associated carrier. If the membrane is torn, the carrier in the background can then easily be detected. A particularly suited brightness contrast between the membrane and the carrier is >0.1. In the case of a desired high color contrast, the color of the membrane should be spaced apart from the color of the carrier by at least 60° on a blue-yellow-red color circle.
