Hearing aids which are custom built to fit the individual shape of a person’s ear canal. The customization is done by taking a silicone impression of the ear canal. That impression is then used by the hearing aid manufacturer to create the custom hearing aid. Custom hearing aids come in several different sizes, including in-the-ear, in-the-canal, completely-in-the-canal, and invisible-in-the-canal.
