March 3 is National Ear Day
It's also World Hearing Day.
This year's theme is
"Caring for Hearing Health, Listening to the Bright Future"
Did you know?
Among every two young people
There is an unsafe way of listening
At risk of hearing loss?
Are you one of them?
Case clinic met a company white-collar Xiao Wang, he often wears headphones to listen to songs to pass the time when he goes to work and takes the subway, and often wears headphones during his leisure time at work, the company's business is relatively busy, making more than 100 calls a day...
Recently, he always feels that his ears are buzzing when he sleeps, sometimes it is particularly loud, it is difficult to fall asleep, and even insomnia all night, and he can also hear the ear ringing when he works during the day on the 2nd day, which seriously affects work and life...
Xiao Wang really can't stand the tinnitus trouble, only to the ear clinic for treatment, the result is that it is the noise caused by deafness and tinnitus, repeatedly asked the medical history, Xiao Wang said that he had no hearing problems, but the hearing examination showed that his high frequency, 4 kHz at the hearing damage, tinnitus matching is also 4 kHz of sound, and the function of external cochlear hair cells shows a decline, is a typical noise-based deafness and tinnitus ...
Noise causes mild hearing loss at high frequencies
Because it was only high-frequency hearing loss, he himself did not perceive the impact of hearing on daily life, that is, because tinnitus called him to the police, he let him know that he not only had tinnitus, but also had hearing damage, which was actually caused by the daily casual listening habits...
The cause is clear, first of all, it is recommended that he stay away from the source of noise, do not wear headphones to listen to music, and try to use hands-free when calling; secondly, to ensure good sleep, not to listen to music or play games for a long time before going to bed; in addition, it is recommended that he usually try to maintain a regular life and exercise, avoid smoking and drinking, excessive pressure, fatigue and other factors that further induce tinnitus.
Do you have some inspiration through Xiao Wang's case? Young people should be very sensitive to sound
Normal audiogram
But if you often wear headphones to listen to music
It is necessary to pay attention to whether it is not clear whether you are listening to other people's voices in a noisy environment
Be vigilant if you have one
Noise can damage your hearing
Because early noise-induced hearing loss is mostly manifested by incisions in both ears or one ear at 4 kHz
The beginning is often undetected
If not prevented
With further damage to the noise
Only then will there be a slow decline in other frequencies
It was too late to find out
Early typical noise-induced hearing loss—a notch at 4 kHz in both ears
In view of the above examples, it is necessary to learn and understand some knowledge about noise on hearing damage so that we can better prevent noise damage!
First, it is important to learn some hearing safety skills, please remember:
1. Loud sounds damage the ears
Listening to loud sounds can damage the sensory cells in the ear,
This can lead to noise-induced hearing loss or ringing in the ears (tinnitus).
2. If you regularly behave in the following ways, you may have hearing loss caused by noise
(1) Work in noisy places.
(2) Listen to music with headphones on your head.
(3) Play loud music at the place you visit, such as a nightclub, a concert, or a fitness class.
3. Hearing loss caused by noise is permanent
The hearing loss caused by noise is irreversible. People with hearing loss can benefit from hearing aids and rehabilitation services.
4. Hearing loss caused by noise can be prevented
Safe listening practices can prevent hearing loss. The louder you listen, the shorter the time to listen safely. By lowering the volume or protecting your ears, you can listen longer without compromising your hearing.
Second, please use these simple safe listening behaviors:
1. Keep the volume low Set the volume of your device to no more than 60% of the maximum volume. Use appropriate noise-cancelling headphones.
2. Protect your ears from listening to loud sounds Wear earplugs in noisy places. Stay away from sound sources, such as speakers.
3. Limit the time to engage in noisy activities in noisy places, and regularly go to a quiet place to rest. Limit the daily use of personal audio devices.
4. Monitor listening sound pressure levels using the app to monitor your sound exposure. Choose a device with built-in hearing protection.
Third, care for hearing, please pay attention to:
1. Be aware of warning signs
Please see a doctor if: (1) Continuous ringing in the ear (tinnitus). (2) Difficulty hearing high-pitched voices or understanding dialogue. (3) Sudden in-ear stuffiness, no obvious cold symptoms.
2. Check your hearing regularly
(1) Use applications such as the World Health Organization recommended by the World Health Organization for hearing self-testing. (2) If you fail the hearing test or show signs of hearing loss, please seek professional help. (3) In a noisy environment, you can't hear other people's conversations clearly, please see an ear doctor to check your hearing in time.
Fourth, block the new strategy of the hidden killer of adolescent hearing
1. Teenagers who wear headphones to listen to music must abide by the "60-60 Principle", that is, the volume should not exceed 60 decibels, and the volume should not exceed 60 minutes at a time. 2. Try to avoid knocking and avoid prolonged exposure to low decibel ambient noise.
