发明名称 Ear mold with vent opening through outer ear and corresponding ventilation method
摘要 A method and hearing aid mold are provided for a hearing device with a first segment for insertion into the auditory canal of the user, a second segment, which projects into the concha of the user when inserted, and a vent, which runs from the first segment into the second segment. A vent opening, which may be enclosed by a titanium ring, is directed in the second segment toward the outer ear of the user, so that an exchange of air can be achieved between the auditory canal and the rear of the outer ear through an opening in the outer ear. Ventilation of the auditory canal from the rear of the outer ear reduces the risk of feedback.
