Two weeks ago, Ms. Wang’s daughter Weiwei got up early to play games in the room. Ms. Wang called several times and didn’t see Weiwei’s reaction. She rushed into the room and asked why Weiwei didn’t answer. Weiwei suddenly covered her ears and screamed, “it’s noisy in her ears, and she can’t hear anything.”

At first, she thought it was a child who was angry and didn’t want to go to school. After two days, Ms. Wang found that her daughter was indeed a little abnormal: she didn’t speak properly and called her not to be. Ask again, daughter still says “cannot hear”. Ms. Wang was so scared that she took Vivian to the hospital. Hearing test found that Weiwei’s left ear hearing was seriously reduced and was diagnosed as “sudden deafness”.

Hearing experts say that in just half a month, they have received 6 junior and senior high school students with sudden deafness. Ask carefully, it’s a game for a whole day, five or six hours in a row.

Jinghao has learned that in recent years, with the popularity of mobile phones, tablet computers and other electronic products, as well as the increase of entertainment places such as cabarets and bars, the risk of noise induced hearing loss of the public, especially teenagers, is increasing.

Foreign research shows that the number of young people with hearing loss caused by new noise in the world is up to 5 million every year. Domestic experts also found in the clinical work that more and more teenagers went to the hospital for treatment due to tinnitus and hearing impairment.

According to the hearing experts, some scholars take 3826 college students in a university as samples and find that 3819 people often use earphones, and the use rate of earphones is as high as 99.8%, including 1070 people with noise induced hearing loss.

Hearing experts analyzed the mechanism of MP3 easy to lead to hearing damage. MP3 earphones are closely attached to the external auditory canal. There is no buffer space for sound to enter the external auditory canal. Strong sound pressure is concentrated on the thin tympanic membrane, causing abnormal excitation of the hearing organ. Under long-term stimulation, the hair cells that feel sound conduction will shrink or reduce, making < A Href = " HTML" target = "_blank" > hearing loss < / a >.

Jinghao understands that short-term, low-intensity noise will lead to temporary hearing loss, accompanied by temporary threshold shift. This kind of damage can be recovered in a certain time after leaving the noise environment. But in the noise environment for a long time, the hair cells are damaged and degenerated, the blood supply of inner ear is reduced, and irreversible hearing loss occurs.
