Method and system for modeling a custom fit earmold

According to an aspect, a method for producing a custom-fit earmold adapted to be securely retained in an ear canal and/ or ear of a user is disclosed. The method includes obtaining a multi-dimensional image of the pinna and/ or ear canal and identifying a plurality of retention possibility points (RPPs) from a plurality of points available at a surface of the image, the plurality of points representing corresponding points at a surface of the pinna and/ or ear canal. Thereafter, the custom-fit earmold utilizing at least one retention point selected from the plurality of RPPs is modeled.
