How To Choose A Hearing AidWhy Do Doctors Say That Hearing Aids Will Make You More Deaf, While Some People Say That Hearing Aids Will Get Better?

Let me talk about the conclusion first: reasonable choice and wearing of hearing aids will not make people more and more deaf, but can protect the central nervous system speech recognition function and cognitive ability of hearing-impaired people.

 

This is similar to the "use it or lose it" in biology. If there is hearing loss without timely intervention, the brain cannot receive sound signals for a long time, and the human auditory discrimination ability and speech recognition ability will decline rapidly. Hearing that was already weak may become worse. Using hearing aids to continuously receive sound stimulation can well stimulate the auditory area of the brain and delay the speed of hearing loss.

 

In addition, researchers from the British SENSE-Cog project published an article titled "Hearing Aids May Slow Cognitive Decline in Old Age" in the journal Hearing Review in 2019. The article proved through a series of complex experiments that after using hearing aids, , the rate of cognitive decline of hearing-impaired persons has been reduced, and wearing hearing aids can effectively reduce the incidence of Alzheimer's disease in middle-aged and elderly persons with hearing-impaired persons.

 

Since wearing a hearing aid has many benefits, why do some people become more and more deaf? I will summarize the main reasons as follows:

 

1. Wearing hearing aids without identifying the cause of hearing loss

 

Hearing loss falls into three categories:

 

The first is conductive hearing loss, which is generally caused by problems with the outer ear and middle ear, such as eardrum perforation, otitis media, clogged storage, external ear canal injury, etc., which generally require medical treatment instead of hearing aids.

 

The second is sensorineural hearing loss, usually a problem with the inner ear, resulting in damage to the auditory hair cells. At this time, we need to wear hearing aids, because the growth of auditory hand cells is irreversible and cannot be treated. We can only rely on hearing aids to stimulate the auditory area of the brain and delay the speed of hearing loss.

 

The third is mixed hearing loss. People with this type of hearing loss have both conductive and sensorineural problems. At this time, the conductive problem should be solved by medical means first, and then the sensorineural problem should be solved by hearing aids.

 

Based on this, it can be understood that patients with conductive hearing loss cannot blindly wear hearing aids. Hearing aids not only cannot solve the actual hearing loss problem, but also threaten the disease, causing the already affected hearing to continue to decline, resulting in "more and more customers" Patients with sensorineural hearing loss can choose to wear hearing aids to delay the speed of hearing loss.

 

2. The type of rib earphone is wrongly selected

 

According to the working principle, hearing aids can be divided into two categories: one is analog hearing aids, and the other is digital hearing aids.

The analog hearing aid can linearly amplify all sounds. It is essentially just a loudspeaker, which is equivalent to putting a large speaker in your ear canal to amplify all sounds in the external environment, including noise. Normal people will listen to the noise at the human volume for a long time
How can you get rid of people who have donated their hearing? Therefore, this type of hearing aid may cause secondary damage to the patient's hearing, which is the culprit of "the more you wear it, the more you become deaf".

 

As for digital hearing aids, they generally have an automatic noise reduction function to respond to changing environments and prevent noise damage to hearing. At the same time, it can automatically identify and highlight the human voice signal to ensure the user's voice recognition rate. At present, the mainstream hearing aids are basically digital hearing aids. This type of hearing aids can protect the hearing, speech recognition ability and cognitive ability of hearing-impaired people, and achieve the effect of "the more you wear, the better".

 

3. Wrong habit of using hearing aids

 

After wearing hearing aids, some people often listen to music and watch videos at the highest volume, or stay in high-noise environments for too long, etc. These wrong usage habits will naturally lead to further hearing loss. Some people buy hearing aids and start wearing them without being adjusted by a professional audiologist. There may be problems such as excessive sound amplification and noise reduction function not turned on, resulting in hearing loss.

 

Of course, in addition to this, there are many reasons for "wearing more and more deafness", such as hearing loss caused by other diseases, normalization of body functions caused by aging, etc., which are not directly related to whether to wear hearing aids.

 

Therefore, when purchasing hearing aids, we must first go to the hospital to understand the cause of our hearing loss. If we really need to wear hearing aids, then it is best to choose a digital hearing aid with noise reduction function and go to a professional fitting agency. Talk about debugging it, and take care of our ears with correct usage habits.

 

The reason why I have a good understanding of the category of hearing aids is because of my grandfather’s recent mental state. The old man was deeply disturbed by his eyes and he basically talked to him by shouting. The old man who used to be happy all day is now Because of deafness, he became taciturn and ignorant of others.

 

I took the old man to the hospital a few days ago. The doctor suggested that he wear a hearing aid, but the old man was not happy on the spot. In his eyes, wearing a hearing aid is equivalent to admitting his own shortcomings, and the always strong old man will naturally not agree easily. At the same time, he heard from other old men that hearing aids cost tens of thousands of yuan at least. He, who has always been frugal, is even more reluctant to spend money on this thing, and he is also reluctant to let me spend money on this thing.

 

Later, I checked a lot of information and told him about the "use it or lose it" mentioned in the beginning and the relationship between hearing loss and dementia. Because of this, the old man agreed to buy hearing aids in fear of complete deafness and dementia.
