Abstract
A hearing aid includes a forward path for processing sound from the user's environment. The forward path includes a) a first microphone providing a first electric input signal representing sound as received at the first microphone, the first microphone being located away from an ear canal of the user, b) an audio signal processor for processing the first electric input signal, or a signal or signals originating therefrom, and for providing a processed signal, c) an output transducer for providing stimuli perceivable as sound to the user in dependence of the processed signal, and d) a second microphone configured to provide a second electric input signal representing sound received at the second microphone, the second microphone being located at or in the user's ear canal, and e) a feature extractor for extracting acoustic characteristics of the user's ear from the second electric input signal, or a signal originating therefrom.
