Zusammenfassung:A method for determining moisture on a covering of a microphone opening of a hearing aid housing without additional components includes determination of an acoustic parameter originating from an earpiece in a microphone signal of a microphone disposed below the covering, comparison of the determined acoustic parameter with a reference parameter characteristic of moisture on the covering, and emission of a moisture signal if the determined acoustic parameter lies within a predefinable tolerance range of the reference parameter. An associated hearing aid and a computer program product for implementing the method, are also provided.
