We know that in old age, the ear may be more or less will be some failure, this kind of hearing loss is commonly known as senile deafness.

 

However, it's not only the inability to hear or communicate that causes senility but also the brain because of aging and loss of hearing ability. Such as slow response, memory decline, and cognitive dysfunction, this is actually the central presbycusis, not simply use into waste back for words can explained clearly.

So how does central senile deafness occur? How should we intervene effectively?

 

This goes back to the development of our hearing and the changes in age-related deafness.

This article will introduce the occurrence of central senile deafness in detail in the form of the story and give effective intervention measures.

 

After about 20 weeks of fetal development, our hearing begins to shape.

We can also hear the sounds of mom’s digestive organs and other body parts.

Because of this connection, it is recommended that mothers adopt singing prenatal education as the first acoustic stimulation.

Since the womb is not soundproof, we can also hear some of the low-frequency noises in our mother’s environment, which we will remember.

After birth, she slowly began to learn more sounds.....

We are born around 40 weeks gestation and our auditory systems mature as we learn to move about our environment and store it as new memories.

 

Remarkably, soon after birth, we recognize our mother's voice. But, because of the lack of awareness and memory of dad’s voice, we didn’t recognize it until a few weeks later.

This shows that listening is a learning behavior, we do not come out of life with perfect listening ability, but need time to develop slowly.

Over time, our nervous system becomes more mature and able to carry more signals from the ear to the brain.

 

Hearing develops slowly before you get old...

By the time we reach age 1, we receive more sound signals but the brain is not at an adult level.

 

However, listening skills develop, such as recognizing the direction of the sound, tolerating noise, listening to the noise, participating in conversation, and keeping up with faster conversations.

 

these listening skills do not reach adult levels until age 12.

From this stage on, our learning, memory storage, and auditory skills continue to develop, so our hearing continues to develop before we get older.

Beginning at about age 50, hearing going downhill......

Listening is innate, and for most of our lives, we take it for granted.

However, when we reach our mid-50s, things change a bit, by age 60, about a third of us have some hearing loss.

By the time we are 75, most of us have developed some degree of hearing loss. During this time, we gradually lose some of our hearing ability and memory for sounds.

Hearing loss, brain degeneration...

Although hearing has deteriorated, sound can still be heard, but it is no longer possible to perceive sound at normal levels and some sounds may not be heard at all.

At this point, most of us may experience hearing problems in noisy environments.

Examples include being unable to hear whispers, asking people to come closer and speak louder, misinterpreting conversations, turning up the T.V becoming less inclined to listen to music or feeling isolated in communication.

Because our listening and verbal communication are controlled by the human ear and brain.

 

Having good hearing allows us to be more socially engaged, and better at learning and memory, thus increasing the activity of the large brain and promoting the development of basic cognitive functions.

If there is no sound stimulation daily, the brain will gradually recede, losing or weakening the ability to process sound.

 

Central senile deafness has occurred......

With the growth of age, and the decline of hearing, the brain will also send changes, senility deafness is in this unconsciously develop into central senility.

Contemporary research confirms that even mild hearing loss accelerates the loss of overall and regional brain volume after approximately 6-7 years.

a longitudinal study of 1100 elderly people with hearing loss for 11 years showed that loss or cognitive impairment was exacerbated.

 

Cognitive function is important for preserving the brain’s sense of reality, because cognitive processes represent thinking, learning, remembering, judging, and solving problems,

May studies have suggested that central senile deafness may be a risk factor for memory loss, dementia, and Alzheimer's disease.

 

Early detection, early diagnosis, early intervention, early rehabilitation......

 

In fact, it seems to be an old saying, early detection, early diagnosis, early intervention, and early rehabilitation of hearing loss.

 

From the above point of view of the occurrence of central senile deafness, we know that at about 50 years of age, the hearing may be going downhill. It is recommended to have an annual hearing examination, which is early onset and early diagnosis.

If hearing loss is diagnosed, it is recommended that hearing aids (e.g. hearing aids) or assistive devices be fitted as soon as possible. These devices help deaf people hear speech and ambient sounds more clearly.

In addition, hearing aids can also people with impaired hearing to retrain some important listening skills, such as hearing sounds around, distant sounds, and sounds from different directions.   

Of course, these devices may not solve all hearing problems, such as trying to hear fast-talking conversations and foreign accents, or background noise caused by damaged nerves and impaired sound processing.

However, they can help people with hearing loss improve in most cases, leading to long-term beneficial changes in brain plasticity, which is an important measure to avoid more serious diseases such as dementia.

 

And an OTC hearing aid.

Subdivision track: non-test match hearing aids usher in development opportunities,

High-end track development trends: OTC, personalized, multi-functional intelligence, and so on.

Unmatched hearing aids have great potential in the future.

The hearing aid products are divided into the fitting and non-fitting modes, which eliminates the need for fitting for hearing loss patients and has a high-cost performance ratio.

It mainly serves users with mild or moderate hearing loss. it can be purchased without offline fitting, eliminating the more complicated fitting link in the middle, and will improve the penetration rate of the hearing aid market.
