Do you often wear headphones to listen to songs and dramas, and unconsciously turn up the volume? Did you wear headphones before going to bed and fall asleep unconsciously?
March 3 is the National Love Ear Day, Li Jinsong, an otolaryngology-head and neck surgeon at Shapingba Hospital Affiliated to Chongqing University (Shapingba District People's Hospital), reminded that using headphones at high volume for a long time will damage hearing, how to wear headphones correctly? Let's hear what the doctor has to say.
Wear headphones often
There may be these hazards
It is understood that there are three types of common headphones on the market: earbuds, earphones and headphones.
Earbuds refer to headphones that are plugged into the ear canal, which are essentially small speakers that transmit sounds such as ** into the ear canal. Because the earphones are close to the ear canal, the range of sound wave propagation is small and concentrated, and the stimulation of the auditory nerve of the eardrum is relatively large. In contrast to the two, the earcups of the headphones provide some cushioning space between the ** and the ear canal, but they are still not recommended for long periods of time.
In noisy environments, users tend to unconsciously turn up the volume of their headphones, but this is likely to be harmful to the ears.
In fact, there is no need to worry too much about which headphones to use, the best way to protect your hearing is to limit the duration and frequency of listening to high volumes**, no matter which headphones are used for a long time, it will cause harm to the ears, especially hearing. Li Jinsong explained that wearing headphones for a long time will cause the environment in the ear canal to be humid and stuffy, which creates conditions suitable for the reproduction of bacteria and fungi.
The doctor also added that wearing headphones for a long time can cause problems such as dizziness, heart palpitations and distraction, and the surrounding environment is ignored, which can easily cause potential dangers and increase safety risks. If you are exposed to high-intensity sound stimulation for a long time and frequently, the hair cells will be overworked for a long time, which may lead to irreversible damage.
How to wear the headphones correctly?
It's important to control the volume, to control the time of use
How to wear headphones correctly? Li Jinsong gave the following suggestions:
First, use the "60-60" principle, that is, the volume should not exceed 60%, wear it for no more than 60 minutes, and let the ears breathe;
Second, try to take off the headphones in a noisy environment, such as during the subway, it is best not to wear the headphones;
Third, regular hearing examinations are essential for early detection of hearing problems, especially for workers in high-noise environments or people who wear headphones for a long time, and regular hearing screening should be carried out to ensure hearing health as early as possible.
It is reported that on the afternoon of March 3, Shapingba Hospital affiliated to Chongqing University will carry out free consultation and health science popularization activities at the entrance of the Three Gorges Square campus. At that time, the expert team will provide free consultation, free otoscopy, hearing consultation, etc., and interested citizens can go to consult.
