1.1 billion young people will be at risk of becoming deaf because of the wrong habit of using headphones
In 2019, the World Health Organization showed that more than half of young people have an unsafe habit of using headphones, and it is estimated that about 1.1 billion young people are at risk of hearing loss due to hearing loss. Improper use of the headset.
Wireless bluetooth headsets are a product that has become very popular lately, but it turns out that wearing such earbuds for a long time, even if you just wear them without listening to music, harm your hearing. Christian Moro, associate professor at Bond University’s School of Health Sciences (Australia), has shown that the ear has a self-cleaning mechanism to push earwax out. However, wearing headphones for a long time will clog the ear canal and prevent earwax from being discharged, causing it to accumulate, which then causes hearing loss, itching and ear pain.
Compared with environmental noise, headphones can transmit sound closer and more focused to the ears, so if you don’t pay attention to the volume or use it for too long, it will damage the sensitive hair cells. and the auditory nerve in the inner ear.
Severe cases can cause permanent hearing damage. For example, the average volume produced by the environment is about 75 to 85dB, if you want to hear the sound of a song or movie, you must adjust the headset to 85 to 90dB.
Hearing is an important channel connecting the brain, once hearing loss, brain activity will become slower, leading to symptoms such as unresponsiveness and memory loss. Professor Moro also pointed out that there are 3 cases where it is not suitable to wear headphones:
1. The outer ear canal is inflamed, injured, or damaged.
2. The skin is allergic to silicone material, if this material is placed in the ear canal, it will cause an allergic reaction to the ear canal.
3. Acute otitis media or cholesteatoma infection and severe ear infections.
The secretions are more likely to contaminate the headphones. Therefore, you should go to the doctor and control the disease, and try to keep the ear canal dry before wearing the headset.
Hearing damage is primarily a chronic build-up. People often experience severe hearing loss without realizing it. Dr. Zhang Yihao, Head of the Taiwan Otolaryngology Clinic, said that the “66” principle should be followed when using headphones, ie the headphone volume should be < 60%, listening time < 60 minutes to reduce the burden. heavy on hearing. In addition, he also recommends the following 4 tips for using headphones.
Limited use time
If you use the headset for a long time, the ear will be constantly stimulated and cannot rest. Therefore, you should limit your usage time to less than 1 hour per day, and take a break every 20 minutes.
If the volume of the headphones is 95dB, it is recommended that you wear them for up to 4 hours; if the sound is loud, such as wearing headphones in the subway, on the street… sometimes it can go up to 100dB, not more than 2 hours max.
Turn down the playback volume
When playing music or watching movies, the volume should be controlled below 60% of the maximum volume of the player to avoid too much energy affecting the inner ear cells and auditory nerves.
Do not use in noisy environments
Many people are used to listening to music to kill time driving, but at this time the environment is very noisy, it is easy to ignore the volume control button to hear clearly.
Use the app to monitor the volume of your headphones
Using the app in the mobile phone to detect the volume of the headset, it can immediately remind the user when the dB is too high, and even help monitor the noise in the environment.
