Q: My son started wearing hearing AIDS six months after cochlear implantation, and now he takes them off in an hour or two. And the sound of purring. What is the reason?
A: Whether the hearing aid and cochlear dual-mode are used well is related to the time to start using the hearing aid and the residual hearing. The selection and debugging of the hearing aid is also very important.
Parents report that the hearing aid has purring sound, which is usually the howling of the outside world, which will affect the children's wearing. Parents can check whether the ear mold is sealed first. Did you put it on? Is there a crack in the sound tube connected to the hearing aid? Or is the hearing aid too loud? Find a fitter to deal with problems in time.
Generally speaking, the causes of hearing aid howling can be summarized into two categories: one is internal hearing aid howling, and the other is external hearing aid howling. )
Reminder: When a child has a dual-mode wearing problem, find out the reason as soon as possible and deal with it as soon as possible. A dual-mode hearing aid with a cochlear implant and a hearing aid can play a binaural listening effect, which is also recommended in China at present.
According to an article published in the Journal of Audiology and Speech Pathology, research shows that binaural dual-mode hearing can significantly improve patients' speech perception, sound source localization and music perception. For patients who are suitable for dual mode, it is recommended to use binaural dual mode listening mode.
Professor Gan's Q&A mailbox is led by Mr. Gan Bingji, a famous audiologist in Hong Kong. He hopes to communicate with hearing-impaired parents and adults through email, and use more than 30 years of rich experience in hearing aid fitting and debugging to further answer questions for more hearing-impaired people.
