  • Method of manufacturing an in-the-ear hearing aid
    Patent number: 5455994
    Abstract: In a method of manufacturing an in-the-ear hearing aid an auxiliary element, whose cross-section is larger than that of an auditory canal, is introduced into the auditory canal. As a result, the auditory canal is expanded. Subsequently, a hollow vent tube is inserted into the auditory canal, after which the auditory canal is filled with a viscous material. After the viscous material has solidified the mold is removed from the auditory canal. The vent tube insures that air is admitted to a space behind the mold. The mold thus formed has a cross-section larger than the cross-section of the auditory canal. Subsequently, a housing for the hearing aid is made, the mold being used as a template. Consequently, the heating aid will fit tightly in the auditory canal, which improves the wearing convenience.
