Abstract
In this study, we investigated the current status of hearing aid functions, wearing conditions, and the selection of hearing aids by surveying facilities for the fitting of infants and toddlers with hearing aids in Japan. Our results revealed that the behind-the-ear type of hearing aid was confirmed to be the most popular type of hearing aid. The desirable functions of hearing aids for infants and toddlers were considered to be, in order, the tamper-resistant volume, acoustic feedback cancellation, noise reduction, a wireless hearing aid system, and directivity. The causes of disruptions in common use and wearing were acoustic feedback, refusal to wear hearing aids, and the hearing aid falling off the ear easily. A common cause of malfunction was sweat. In the selection of hearing aids for infants and young children, concerns such as a reduction of the economic burden, a shape that fits the auricle, and waterproofing performance were emphasized. The need to replace new hearing aids because of a child's growth can create an economic burden for young parents of hearing-impaired infants. Hearing-aid fitting programs for hearing-impaired infants and their parents are needed and should be held in close cooperation with specialists involved in rehabilitation.
