The reason is not difficult to understand: long-term use of headphones, because the eardrum is very close to the earphone diaphragm, the sound wave propagation range is small and concentrated, which stimulates the auditory nerve of the eardrum greatly, easily causing ear inflammation, tinnitus, hard of hearing and other symptoms, and the auditory nerve can not get a good rest, leading to hearing loss or even loss.
In view of this, the following suggestions are put forward: 1. Try to listen to music with speakers, followed by headphones. The hearing safety index of headphones is from high to low: speaker >; Wear > ordinary earplugs > ear hook > earplugs.
2. When choosing headphones, choose the one with good texture and low noise.
3. Use headphones for no more than 30 minutes at a time and no more than 3 hours a day. Not too loud, you can hear it.
4. Always do ear exercises, such as gently pulling the earlobe and stroking the bones outside the ear.
If you have any discomfort in your ears, you must see a doctor as soon as possible, and don't miss the best treatment time.
Attach the correct way to wear headphones.
