Do you often feel like you can't always hear what people are saying?
Do you always have to turn on the sound of the headphones to a very large size, and always speak unconsciously loudly?
Does your ear always "buzz", often with some noise and noise?
This shows that your ears have been "irreparably" hurt.
More and more people are turning into "little deaf people"?
According to the World Hearing Report released by the World Health Organization, 1/5 of the world's people are currently hearing impaired, and hearing loss affects more than 1.5 billion people worldwide.
In fact, hearing and language disabilities in the mainland are the first of the five major disabilities such as visual disability, limb disability and intellectual disability, and from 2008 to 2018, the number of people with hearing loss in the mainland increased by 22 million. Among them, the elderly have the largest number of hearing disabled people, and if they can intervene as soon as possible, the quality of life of the elderly will be greatly improved.
According to the World Health Organization, about 1.1 billion young people aged 12 to 35 around the world are now at risk of irreversible hearing loss, and one of the culprits is the high volume of headphones just mentioned.
It can be said that when hearing is damaged, no earphone is innocent.
In addition to directly causing damage to your hearing, wearing headphones and pulling out your ears will also engage in "roundabout tactics" and change the law to affect your hearing.
In the long run, it may lead to hearing loss and even become a "little deaf person". Hearing loss is still an almost irreversible symptom at the medical level of today's world.
So how do our ears get damaged?
Contemporary young people go out in a three-piece suit: mobile phone, mask and headphones. Many people like to wear headphones in a noisy environment, in this case, in order to hear the sound in the headphones, they will unconsciously turn up the volume of the headphones, but they do not know that they have exceeded the range that the ears can bear.
In general, a volume above 85 decibels is likely to cause auditory fatigue, and a volume above 110 decibels will cause the death of hair cells in the inner ear. It can be said that when hearing is damaged, no earphone is innocent.
Our ears don't actually like to be too clean. The skin of the cartilage part of the external auditory canal has cerumen glands, and its yellowish viscous secretion is cerumen, commonly known as "ear feces". Cerumen has the effect of protecting the skin of the external auditory canal and adhering to foreign objects, usually by chewing, opening the mouth and other exercises, cerumen will continue to discharge the ear canal by itself. If the "ear feces" is as hard as stone or soft as mud, most of them are close to the external ear canal, and it is not easy to move, and this situation must be treated in a regular hospital, and cannot be cleaned up by yourself.
If it is not properly managed on its own, the external auditory canal wall is destroyed or inflammation occurs, which will cause the external auditory canal to accumulate too much to form a cholesteamoma, and the cholesteamma will become larger and larger, and continue to destroy the skin and even bone of the external auditory canal. If the ear collection tools are not strictly cleaned and disinfected, there is a risk of infection and cross-infection.
Some bumps, slaps, pulls, and even sucking on the ears can cause traumatic tympanic membrane perforation, resulting in hearing loss.
So in order to protect our ears, we must pay attention to the following precautions:
■ Safe use of headphones, follow the "60-60 principle", that is, the use of headphones does not exceed 60 minutes, the volume of headphones does not exceed 60% of the total volume, or the use of headphones for no more than 40 hours per week, and try to keep the volume within 80 decibels;
■ Do not use headphones in noisy environments such as subways to reduce the need to improve sound, or use noise-canceling headphones;
■ Wear earplugs in noisy places such as dance halls, bars, sports events, or stay away from noisy environments such as KTV, bars, and discotheques, or minimize the time of continuous exposure;
■ When exposed to high-intensity noise for a long time, strict protective measures should be taken and anti-noise earplugs or earplugs should be worn;
■ Limit the daily use of personal audio, monitor the time and volume range of your headphones, and know the safe listening;
■ For workers with noise contact environments, regular hearing checks should be made.
Once the hearing is damaged, it is really irreversible
Regardless of the length of time, as long as the ear is exposed to a huge high-decibel noise, it will cause fatigue of the auditor's sensory cells, and then temporary hearing or tinnitus.
However, if the exposure is prolonged or the volume is particularly large, it may last for a long time, which will trigger permanent damage to other structures of the sensory nucleus, resulting in irreversible hearing loss.
Gradual loss of hearing can affect speech comprehension, which can negatively affect an individual's quality of life.
Therefore, I would like to advise young people to protect their little hearing.
Keep the volume low, use the right headphones, limit the amount of time you spend each day using your personal audio equipment, pay attention to the level of hearing safety, wear earplugs in noisy places, etc.
All these details can prevent our hearing from suffering greater damage.
As the saying goes: look at the six ways, listen to the eight directions.
Whether it is hearing or vision, we all need to guard it well.
