Every day I work or study after I’ve been tired, I’ll choose to plug in a headset to listen to the song. This will not only affect other people, but also play a happy and busy experience. However, it is not good to have more earphones, which can cause damage to the cochlea cells and severe hearing damage.
The correct use of headphones
1, pay attention to the volume and use of time
Dizziness, tinnitus, ear plugs, or wearing headphones for more than 3-4 hours a day, are at high risk of hearing impairment. Experts suggest that the sound of wearing headphones should not exceed 2/3 of the maximum volume of the player. After listening for 30-40 minutes each time, the ears should be fully rested. The volume of the earphone should be as close as possible to the sound of a normal person, preferably 50-60 decibels, not more than 85 decibels;
Adults do not wear headphones for more than 3-4 hours a day, minors do not exceed 1-2 hours a day, and 30-40 minutes after wearing headphones, they must fully rest their ears.
2, headset headset is better than in-ear headphones, long-term use is recommended to choose the former.
For people who need to wear headphones for a long time, it is recommended to choose a headset. The in-ear earphone has a small sound contact area, and has a large pressure inside the cochlea. The earphone has a large contact area and a small pressure, and the stimulation to the cochlea ciliated cells is relatively small and safe.
In addition, the received sound can be transmitted through the skull in addition to the air conduction pathway. In particular, when students are listening, they can listen to headphones and wear headphones. They can also hear sounds and reduce the stimulation of the cochlea.
3, the use of headphones environment is also very important.
We can often see some young people in the noisy streets, listening while walking or listening to the car, or even listening to riding a bike, in fact, in a quiet environment, earphone damage to the ear is least, and then before going to bed Listening for a while can also reduce injuries, and ear damage can be greatest when using headphones on a noisy subway or on a car.
Although headphones are a good tool, they should be used rationally. After using the headset much more attention oh.
