It does not affect others but also entertain themselves. However, experts have warned that wearing headphones for a long time, especially if they are used to listening to loud songs, will lead to progressive hearing loss.
How to use the headset correctly?
Wearing earphones damage hearing is a gradual, easy to ignore long-term wearing headphones will not only damage hearing, but this damage is difficult to regenerate. Like other senses, there is a specialized hearing "receptor" in the ear - the cilia cells in the cochlea. We can hear the sound because the susceptor is stimulated and the cilia vibrate with the sound.
The correct use of headphones 1, pay attention to volume and use of time dizziness, tinnitus, ear plugs, or wear headphones every day for more than 3-4 hours, are hearing vulnerable high-risk groups. 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.
