New Earmold for Children

Abstract

The howling effect in use of hearing aids among infants and children used to be a frequent and common problem in the past. The narrowness of their ear canal, their physically active nature and, use of high-powered hearing aid derived from severe hearing loss were accounted for the occurrence of howling effect. Furthermore, their little and tender auricles created a disadvantage in fitting a hearing aid.
‘The Ear Mold for Children’ is the meliorated version of its predecessor ‘Improved Ear Mold’ which was developed mainly for senior users. The main improved features for this new type of mold are; 1) resilient entering part of the ear canal can enhance close fitting and easy handling, 2) flexible body of the mold creates further fitness, 3) tightly attached tube between the hearing aid and the ear mold generates high stability.
After putting ‘The Ear Mold for Infants and Children’ to trial, we found that it not only eliminated the howling effect but also steadied the hearing aid into the ear. We created the hearing aid that is comfortable to hear and easy rest behind the ear.
