1. A method for checking a usability of an impression model of a human ear and for manufacturing at least a part of a hearing device, the method comprising:
determining the impression model by scanning the human ear or an ear impression of the human ear with a scanner;
determining, by an evaluation device, an estimated shape model of the human ear by adapting a statistical shape model to the impression model, wherein the statistical shape model has been determined from a plurality of impression models of a plurality of human ears, wherein adapting the statistical shape model to the impression model is performed by deforming the statistical shape model such that an objective function, which measures a difference between the impression model and a deformed statistical shape model, is minimized, and wherein the statistical shape model has at least one impression feature, which is mapped in the adaption process of the impression model to the estimated shape model to an estimated impression feature of the estimated shape model;
determining, by the evaluation device, a feature classification from the estimated impression feature; and
when the feature classification is within an allowed feature classification range, rating, by the evaluation device, the impression model as usable; and
manufacturing, by a manufacturing device, at least part of the hearing device based on the impression model when the impression model is rated as usable.
