According to the World Health Organization, about 1.1 billion young people worldwide are at risk of irreversible hearing loss. Exposure to noise in the entertainment environment and excessive volume of personal audio devices are the "main culprits" of hearing loss. Coupled with factors such as staying up late, alcoholism, stress, and excessive use of the ears, sudden deafness is frequently befalling teenagers.
For those suffering from hearing impairment, not being able to hear is closing a window to the world, and once hearing is lost, it cannot be restored.
In fact, "sudden deafness" is a common emergency in otolaryngology, and the onset of hearing loss often occurs without any warning, and the onset is relatively acute, usually a few hours or a day or two. It is generally accepted that when the average hearing threshold of the language frequency is above 26dB, it is called hearing loss or hearing impairment. Depending on the degree of hearing loss, it is also called hard of hearing, hearing impairment, hearing loss, hearing loss, etc.
Deafness refers to the phenomenon of lesions in the auditory nerve and centers at all levels in the auditory system, which causes auditory dysfunction and varying degrees of hearing loss. Most people who are deaf have very severe hearing loss, which means they are barely or completely unable to hear, and they often communicate with sign language. Sudden deafness, also known as idiopathic sudden hearing loss, or "sudden hearing loss" for short, refers to sudden, unexplained sensorineural hearing loss.
The main clinical manifestations are unilateral hearing loss, which may be accompanied by tinnitus, ear blockage, dizziness, nausea, vomiting, etc.
In the past, sudden deafness was more common in middle-aged people in their forties and fifties, but now, "sudden deafness" is frequently coming to teenagers, and young people in their twenties and thirties can account for 30%. The cause of sudden deafness is not well understood, but it is generally believed that it may be related to viral infections, autoimmune diseases, vascular lesions, and other factors.
Wearing headphones often can have serious consequences. According to the data, 17% of adolescents in South Korea suffer from "noise-induced deafness". The irrational use of headphones is "damaging the ear and invisible".
If you listen at a volume above 89 dB for up to 1 hour a day and continue for 5 years, you may lose your hearing permanently. When wearing headphones, you should strictly follow the "60-60-60" principle: the volume should not exceed 60% of the maximum volume, and it is best to adjust it to a lower level; Do not use the headphones continuously for more than 60 minutes; It is best not to exceed 60 decibels of external sound.
It is important to emphasize that you should never sleep with headphones on. During sleeping, the posture is difficult to control, which not only causes noise damage, but also easily compresses the headphones, causing physical damage to the fragile ears. In noisy public places, try to avoid listening to songs.
When you find that you can't hear clearly when the volume is turned up to 60% in a noisy environment, it's time to take off your headphones, and continuing to listen will only damage your ears. It is also recommended to use headphones with noise cancellation.
