Deafness is also called hearing loss. Hearing loss is called more professional. Deafness is our common name. But in fact, most hearing loss patients prefer to be called hearing loss rather than deafness.
Let’s learn a few facts about deafness.

About 34 million of these 466 million people are children. If we don’t take measures, the number will increase to 630 million by 2030 and may reach more than 900 million by 2050.
Fact two does not deal with hearing loss, which will cause us $75 million loss to the world every year.
It’s a huge number. Maybe many people think it’s deafness. How could there be such a big loss? In fact, these losses include education, health, employment, intervention in deafness, prevention, treatment, research and development of hearing aids, etc.
In fact, many people have different levels of hearing loss from the age of 45.

It is inevitable, but it is only a matter of age, but it will have a certain impact according to your daily life habits, but it is undeniable that there are cases of 80 year old hearing still alive.

Here, young people refer to 12 to 35 years old, entertainment noise such as concerts, KTV, bars, etc.
In fact, the output of hearing aids can’t keep up with the demand.
