Headphones are taking away hearing. Wearing headphones is too loud.
According to the WHO, about half of the world's young people are using a mobile phone and other devices to listen to music at a higher volume than safe. WHO Director-General Tan Desai said that hearing loss is often irreversible. In the case that human beings have sufficient skills and knowledge to protect hearing, many young people should not be exposed to hearing loss simply because they listen to music.
"This argument is well-founded. It is a bad habit to wear headphones for listening to songs for a long time." The reporter interviewed the ear specialists of the Second and Third People's Hospitals in Chengdu. In their view, the high-intensity voice constantly Impact on the eardrum can cause damage to tissues such as hair cells in the cochlea, especially affecting people's ability to perceive high-frequency sound.
Why is it causing irreversible damage?
The hair cells in the inner ear are not regenerable, and data released by the WHO indicate that young people are more interested in contact with entertainment, especially the noise from personal audio equipment. Zhang Jianhui said that sounds above 85 decibels may cause damage to human hearing. Even if you usually pay attention to the volume when listening to music with headphones, some of the volume in the music will exceed 85 decibels. "There is 5-10 minutes in 1 hour, which usually exceeds the tolerance of people." Hu Chunhong thinks Although this kind of noise is difficult to seriously damage hearing in the short term, in the long run, the damage is chronic. What is the mechanism of noise-induced hearing loss? For example, it is like a high-intensity sound that constantly hits the eardrum, thereby damaging the hair cells, nerves, blood vessels and other tissues in the inner ear. Hair cells are not regenerative, one less one, which is why it causes irreversible damage. So don't turn the headphone volume too loud at any time. Both doctors told reporters that short-term, temporary hearing loss can be improved through rest and treatment. Long-term noise stimulation will result in a slow, progressive hearing damage. Hair cells with a diameter of only 0.01 mm cannot be regenerated after injury, and there is no effective treatment. They can only be remedied by cochlear implants.
Suggest:
1. Do not exceed 60% of the volume, do not exceed 60 minutes.
People who often wear headphones to listen to music should master the "60-60" principle, which is also an internationally recognized method of protecting hearing. "That is, when listening to music, the volume should not exceed 60% of the maximum volume. More than 60 minutes." In addition, the headset is best to choose the head-mounted type, it is less damage to the hearing than the earphones, because the earphones are directly plugged in the external auditory canal, the sound is not from the source, they are sent to the tympanic membrane, all are The tympanic membrane receives more damage to the hearing.
2. Try not to listen to music in a noisy environment. It is best not to wear headphones when listening to songs indoors.
Try not to listen to music in a noisy environment. In subways and buses, people will inevitably turn up the volume. When listening to music indoors, it is best not to wear headphones to listen to the music outside, the sound through the auricle and then into the ear canal, is a more natural state.
3. Tinnitus, ear nausea, inaudible sound, leave the high-decibel music environment as soon as possible
When listening to songs at high load, causing tinnitus, ear nausea, dizziness, inattention, and inaudible sounds, it indicates that the ear is alerting, which may be an early sign of hearing loss. The doctor recommends that you leave as soon as possible. High-decibel music environment, pay more attention to rest in a quiet environment. In addition, a reasonable diet, less staying up late, and participating in physical exercise are also good ways to protect your hearing.
4. Hearing damage is difficult to cure for more than 3 months and should be checked regularly
In general, hearing damage caused by noise can usually be cured if it can be seen within a week. When the hearing damage is more than 3 months, it is permanent and difficult to cure. The sounds that humans use for communication are in the range of 200-2000 Hz, and the damage caused by wearing headphones to listen to music usually affects people's perception of higher frequency sounds, that is, above 4000 Hz, so it is difficult for ordinary people to detect themselves. The doctor recommends regular checkups and find problems in time for treatment.
