The human auditory nerve will also “use in and out”, it is recommended to wear hearing aids

约翰·霍普金斯大学的Frank Lin教授对600名年龄在36~90岁的男性和女性进行了长达12年的调查后发现,听力损失是诱发老年痴呆症的独立的病因。排除年龄和其他因素影响,患有轻微听力损失的人与听力正常的人比,日后患痴呆症的可能性要高出两倍;大概有9%的受试者在研究期间,均患有不同程度的痴呆症,并认为听力越差的人,患老年痴呆症越严重, 换言之,如果患有听力受损,将大大增加患痴呆症的几率。

If a patient with both ears wears only one Hearing aid , The ability of the ear that is not wearing a hearing aid to understand language will gradually decline. Audiology calls this phenomenon the late-onset hearing deprivation effect.

According to statistics, the incidence of this phenomenon in 7 months to 4 years is as high as 33%.

The decline in language comprehension may be due to the ears with hearing aids sending enough information to the brain, so that the brain no longer pays attention to the ears without hearing aids, and the brain seems to give up on the ears that transmit weaker signals.

Clinically, for people with bilateral deafness, if there are no other influencing factors, it is recommended to wear both ears in order to avoid further deterioration of language ability in the ears without hearing aid Hearing aid .

Wearing hearing aids in both ears can not only increase the amount of information received by the auditory center and improve language understanding, but more importantly, in case of sudden hearing loss in one ear (such as sudden deafness), then the other ear has enough language Comprehension ability to undertake the task of language communication.

If the patient insists on wearing only one hearing aid, he should monitor the binaural hearing and speech recognition rate while wearing the hearing aid, and use the left and right ears alternately
