Abstract
A hearing aid to be worn completely in the auditory canal and is adaptable to an individual auditory canal, is individualized by casting of a body in an auditory canal or in a model of an auditory canal. The body is cast in a casting cavity (15) at least partly confined by an extensible membrane (14). In its general condition, before or especially during casting, the inventive hearing aid carries a positioning tip (20) which surrounds the innermost part of the hearing aid radially completely. This positioning tip (20) which is designed to have the form of a tube or of a cap serves for centering the innermost part of the hearing aid when it is introduced into the auditory canal or into the model of such a canal for individualization. After the casting of the body the positioning tip (20) is removed. The innermost part of the individualized appliance, after removal of the positioning tip, is orientated relative to the body of the appliance such that it does not touch the wall of the auditory canal when the hearing aid is worn.
