On the effect of hearing aids

Deafness, audiology is called hearing loss and hearing impairment. According to the location and nature of the lesion, it can be divided into conductive hearing loss, sensorineural hearing loss and mixed hearing loss. Some conductive hearing loss can be treated by medicine or surgery, but there is no ideal treatment for sensorineural hearing loss. It can only be solved by hearing aids or cochlear implants.

As the name suggests, “hearing aid” is a tool to assist in listening to sounds. It has no therapeutic effect.

Some hearing loss patients always enlarge and idealize the effect of hearing aids when they choose them. They hope that they can have normal hearing if they wear hearing aids. In fact, hearing aid is only a special sound processor. It can amplify and adjust the external sound according to the needs of patients, so as to meet the requirements of hearing compensation for hearing loss patients, and meet the daily life and work needs of patients with hearing impairment. It cannot replace the real ear. So we should have a correct understanding of the effect of hearing aids and a reasonable expectation.

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

1. The degree of hearing loss. Hearing aids are more suitable for patients with moderate hearing loss, and the effect is better. In addition, there are many models to choose. However, the effect of mild hearing loss and severe hearing loss is worse. Extremely severe hearing loss is the worst, and the choice of models is very limited.

Second, the length of hearing loss and the time of hearing intervention. After finding the hearing loss, the patients should be treated or intervened in time, and choose hearing aids or other rehabilitation methods. The earlier the intervention, the better the effect of wearing hearing aids.

Third, the difference between pre – and post lingual deafness. Because the patients with prelingual deafness have no language basis, all speech needs to rely on the clarity of hearing aids to learn language. So there are higher requirements for the size of age. The patients with post-verbal deafness have language foundation, so they need hearing aids to improve their voice and achieve the purpose of listening clearly. So the effect of hearing aid wearing is better than the former.

4. Diseases causing hearing impairment and pathological location. The effect of hearing loss caused by different diseases is also different. For example, the hearing loss caused by radiotherapy of NPC will be greatly affected, and there will be some instability. There are also some diseases such as otosclerosis, otitis media, cholesteatoma, Meniere’s disease, acoustic neuroma and so on.
