This time I believe what the experts said, and the experts said that it is really not recommended to wear headphones for a long time! Once the hair cells are damaged irreversibly and hearing is damaged, no pair of headphones is innocent! Although we can't feel it when we are young now, as long as you wear headphones for a long time and go to the hospital for examination, there will be some degree of damage.
At birth, the human body equips the cochlea with less than 20,000 auditory hair cells to sense sound. If you wear headphones for a long time, the headphones are very close to your ears, and if the volume is loud, it will damage the hair cells, and once the damage is basically irreversible.
In this regard, medical staff suggest that there are three principles that should be mastered in the use of headphones, and these three points must be taken a good look at, if you like to wear headphones, then you must pay attention to them. 1. The environmental noise floor shall not exceed 60 decibels. 2. The headphone volume is less than 60% of it. 3. The use of headphones at the same time should not exceed 60 minutes.
The reason is very simple, I am the victim, I don't use headphones now, I have ear pain after wearing headphones for a long time, and otitis media, this is because I can't wear headphones anymore after wearing them for a long time. Although high-tech is very advanced now, it has also improved our quality of life, but why are many of these high-tech products harmful to the human body? So how long do you wear headphones every day?
