Abstract:
1. A method of computer-assisted analysis of ear canal data characteristics for a hearing aid impression, comprising: obtaining a 3D data representation of the impression; performing a classification on the 3D data representation of the impression to define impression regions, including a canal; defining a total number n of slices of the canal; slicing the canal into n slices; for each slice: the method further comprising: performing a basic classification of external canal morphology based on the parameter values for each of the slices to classify the canal as having a shape selected from the group consisting of a conical or tapering down shape, a bulb or tapering shape, and a cylindrical or non-tapering shape; determining the angular shape of the canal based on angular measurements that characterize changes in the canal shape towards the inner ear and beginning at the aperture; and outputting, via a system output, information related to the canal based on the classification information relating to the slice cross-sectional shape, the external canal morphology, and the canal angular shape and the slice information.
