Male students a prank, 13-year-old girl instant deafness!

A few days ago, a class break, Xinxin back seat students from the bag out of a bag of bread to play. All of a sudden, the students broke the bag with a bang, and the sound of the break resounded throughout the classroom.

Although the sound is very loud, but the students are not scared, because many students often play this “pat the bag” game, feel that the “bang” sound generated after the bag is broken is very fun.

But, what never thought of was that the accident happened! Xinxin’s right ear, which was sitting in front of her, suddenly began to ache, accompanied by a strong tinnitus. Later, she could not even hear it. After that, Xinxin was rushed to the hospital.

Knock deafness, recovery rate is only 50%

The doctor immediately examined Xinxin’s ear function, and the result showed that she had moderate sensorineural deafness!

After questioning, Dr. Zheng learned that Xinxin had no problem with her hearing before. The culprit may be the bag that was shot.

“This is explosive deafness, because the shock wave generated after a loud noise will travel along the ear canal to the tympanic membrane, and finally hurt the child’s inner ear nerve, resulting in sudden hearing loss.” The doctor sighed: “Xinxin’s right ear hearing recovery rate is only 50%, it may not be cured for a lifetime.”

Why is the small bag so lethal?

Maybe many people can’t believe it. How can a small bag deafen people?

Detonation deafness is caused by impulse noise (or pressure wave) to damage the hearing organs, which leads to different degrees of hearing loss. Most of the ears are asymmetric acute injuries, accompanied by tinnitus, earache, dizziness and other symptoms. There will be hearing impairment, serious or even complete loss of hearing.

Why are other children OK, only Xinxin has symptoms?

The function of the inner ear of the elderly and children is degraded, and the structure of the ear of children is not perfect, which is the most vulnerable. In addition, blast deafness is related to distance and direction of blast source, location, age and individual difference of patients.

That is to say, not all people will have knock deafness when they encounter a loud noise. But it’s possible for everyone, so be careful.

So in life, we should pay attention to fireworks, balloons and so on! If you are unlucky, the early symptoms include severe earache, tinnitus, instant hearing loss, sometimes vertigo, nausea, vomiting, etc., and even coma, concussion, deafness of both ears!

The best way to avoid explosive deafness is to prevent it. If you encounter an environment with great noise, you can cover your ears with both hands and open your mouth to reduce the impact of shock wave on your inner ear.
