Patent abstract
The aim is to be able to determine the spatial structure of an ear canal in a simple and reliable fashion. To this end, it is proposed to produce a hologram of the ear canal, by inserting a holography unit at least partially into the ear canal. The data for the shape of a housing shell or an otoplastic can then be obtained from the resulting hologram for automatic manufacturing methods.
