How loud is the decibel?Have you heard of it?

Q

How does noise damage our hearing?

A

Noise is one of the culprits that lead to deafness. Although the ears have a certain self -protection mechanism, a one -time contact with huge noise or a long time listening to high frequency will cause the protection mechanism to fail. Disposable contact will cause damage to the cells and membranes of cochlea, and long -term contact will cause excessive fatigue and damage to the hair cells in the cochlea, and cannot be renewed. In addition, the synapse of the hair cells and the nerve will also be damaged, causing concealment of hidden hearing loss. Even if you stop contact with noise, harmful effects may continue. These injuries are permanent. In order to avoid damage to the ears, we should change the habit of wearing headphones for a long time, and we should also avoid covering the noise of the environment with the sound in the headset and avoid exposing the ears to the environment of the super decibel for a long time.
