What is it like to have poor hearing?
When chatting, you always need to repeat the other person, turn on the volume of your phone or TV, and often miss the doorbell or ringing of the phone......
People often think that "behind the ear" is for the elderly, but nowadays, there are more and more young people with hearing loss.
More and more young people are hearing loss
The World Health Organization estimates that more than 1 billion people aged 12~35 are at risk of hearing loss worldwide.
A survey of 2,000 people conducted by Talker Research, a polling agency in United States, found that 35% of respondents said that they were excluded from crowd chats because they "couldn't hear clearly", and 23% of "post-90s" and "post-00s" felt this feeling particularly obvious.
Research by the France Hearing Center shows that 70% of young people aged 17~28 have tinnitus.
A study by Seoul National University Hospital in Korea found that 17% of adolescents experienced noise-induced deafness.
In mainland China, young people also have varying degrees of hearing loss. The incidence of tinnitus is increasing year by year, and young and middle-aged people account for 2/3 of the total number of patients.
Gao Liuhua, chief physician of the deafness and tinnitus clinic of Beijing Royal Hospital of Integrated Traditional Chinese and Western Medicine, said that the hearing loss of the elderly is mostly due to age, the gradual decline of neurological function, coupled with chronic diseases such as arteriosclerosis, hypertension, coronary heart disease, diabetes, etc., which leads to insufficient blood supply to the head and inner ear, and hearing loss. Hearing loss in young people is mainly related to lifestyle.
Wear headphones for long periods of time
Many people are accustomed to wearing headphones to watch videos, listen to music, and sometimes wear headphones to listen to songs when crowding buses and subways.
Under normal circumstances, the comfortable volume that people can feel is not more than 40 decibels, but the ambient noise tends to reach 70~80 decibels.
In noisy environments, the volume must be amplified to more than 30 decibels of the ambient sound to be heard, and this close-up, long-term, excessive stimulation can damage the auditory hair cells, which can lead to ear pain, tinnitus, hard of hearing and even hearing loss.
Too much stress
Being exposed to negative emotions such as high-intensity stress, tension, and anxiety for a long time will cause insufficient blood and oxygen supply to the brain and auditory nerves, and the microcirculation of the inner ear will be impaired, causing tinnitus, hearing loss, and even sudden deafness.
Stay up late often
In general, young patients with tinnitus and deafness often have a period of excessive fatigue before the disease.
For example, many white-collar patients reported that they had worked overtime continuously before their deafness, slept less, and felt very tired; Most of the students reported staying up late before the exam.
Two methods self-measure hearing health
Song Haitao, chief physician of the Department of Otolaryngology of Beijing Hospital, reminded that because there is no detailed hearing examination in the routine physical examination, patients who come for examination often have ear congestion or tinnitus. If you wait until your hearing loss to get checked, it's already more serious.
If young people find that they often can't hear others clearly, ask the other party to say it again, need to increase the volume of mobile phones and TVs, have tinnitus in quiet or normal conditions, and are said to speak loudly, etc., they must be vigilant and seek medical examination and treatment in time.
There are many cases of sudden tinnitus and deafness in clinical practice, and many people are found by chance. There are two ways to self-test and mutual hearing test.
Surface acoustic detection
In a quiet room, plug one ear and listen to the second hand with the other ear at a distance of 80 centimeters from the clock. If it can be heard, it is considered normal; If you need to shorten the distance to hear, it means that your hearing has deteriorated.
Voice detection
In a quiet room, the subject stands on one side of the tester and plugs the other ear, and the two people should be 6 meters apart; If the tester speaks in an airy voice, it is normal for the person to be able to hear clearly, but if the distance needs to be shortened to hear clearly, it is a decrease in hearing.
4 details to protect your hearing
The most terrible consequence of hearing damage is irreversible, because the auditory hair cells have no ability to regenerate, their number is fixed, and once the cells die, the hearing damage is permanent. Pay attention to the following details in your life to help your ears protect your hearing.
Pay attention to ear hygiene
Keep the ear canal dry, don't pluck your ears frequently, if there is more cerumen and it affects your hearing, you can go to the hospital regularly to clean it.
There is a "60-60-60" principle when wearing headphones
No matter what kind of headphones you wear, don't let the volume exceed 60% of the total volume, don't listen for more than 60 minutes at a time, preferably no more than 60 decibels of outside sound, and don't sleep with headphones on.
Pay attention to the way you blow your nose
Do not press and hold both noses hard at the same time. This causes a sudden increase in pressure in the nasal cavity, causing secretions with bacteria and viruses to be pressed along the Eustachian tube into the middle ear cavity, increasing the risk of middle ear infection and causing hearing damage.
Have regular hearing tests
The average person has a hearing test once a year; Workers in special industries, such as the decoration industry, entertainment venue workers, construction industry, etc., are recommended to be inspected twice a year.
