Deafness, audiologically calledHearing loss, Hearing impaired.According to the location and nature of the lesion, it is divided into: conductive hearing loss, sensorineural hearing loss and mixed hearing loss.Partial conductive hearing loss can be treated with drugs or surgery, while sensorineural hearing loss currently has no ideal treatment.Hearing problems can only be solved with artificial devices such as hearing aids or cochlear implants.

“Hearing aid“As the name suggests, it is a tool to assist in listening to sounds, and it does not have a therapeutic effect.

Some patients with hearing loss always expand and idealize their effects when choosing hearing aids, hoping to have normal hearing when they wear hearing aids.In fact, a hearing aid is just a special sound processor. It can amplify and adjust the external sound according to the needs of the patient to meet the hearing compensation requirements of the hearing loss patient and meet the daily life and work needs of the hearing impaired patient. It cannot replace the real ear.Therefore, we must have a correct understanding of the effect of hearing aids and reasonable expectations.

The effect and suitability of hearing aid selection usually depend on the following factors:

XNUMX. The degree of hearing loss.Hearing aids are more suitable for patients with moderate hearing loss, and the effect is better.And there are more choices in models.On the contrary, the effect of mild hearing loss and severe hearing loss will be worse.Extreme hearing loss is the worst, and the choice of models is also very limited.

XNUMX. The length of time of hearing loss and the time of hearing intervention.After the hearing loss is discovered, the patient shall promptly perform treatment or hearing intervention, and choose hearing aids or other rehabilitation methods.So the sooner the patient intervenes, the better the effect of wearing hearing aids will be.

XNUMX. The difference between pre-lingual deafness or post-lingual deafness.As patients with pre-lingual deafness have no language foundation, all speeches need to rely on the clarity of hearing aids to learn language.Therefore, there are higher requirements for the size of the age.Post-linguistic deaf patients have a language foundation, and they need hearing aids to improve their voice to achieve the goal of hearing clearly.Therefore, the effect of wearing hearing aids will be significantly better than the former.

XNUMX. Diseases and lesions that cause hearing impairment.The effects of fitting hearing aids on hearing loss caused by different diseases are also different.For example, the hearing loss caused by radiotherapy for nasopharyngeal cancer will have a great impact on the effect, and there will be some instability.Other diseases such as otosclerosis, otitis media, cholesteatoma, Meniere’s disease, acoustic neuroma, etc. are also different.
