Urban white-collar workers have a high incidence of sudden deafness, most of which are caused by over-use of headphones; “enjoyment” becomes “destructive”, “headphone family” beware——
Listening to headphones on the subway hurts your ears the most
◆ A scientific study in the United Kingdom shows that wearing headphones for a long time to listen to songs can cause deafness 30 years in advance.
◆It is best to choose a headphone, which has less damage to hearing than earphones.
◆When listening to music with headphones, the volume should not exceed 60% of the maximum volume, and the continuous listening time should not exceed 60 minutes.
Nowadays, listening to music on MP3 or mobile phone has become a popular among young people.In the bus, in the subway, on the street…in any corner where people come and go, you can see fashionable men and women wearing various headphones and listening to music passing by.However, as everyone knows, while we are totally indulged in the world of music, our ears are undergoing severe “tests”——
Listening to headphones on the subway hurts the ears, listening to songs and chewing gum to protect your ears
The “headphone family” is deaf or 30 years in advance
Beckham, who loves rock music, often puts a pair of headphones in her ears, especially in places with noisy sounds such as shopping malls and subways. In order to make her hear more clearly, she will consciously turn up her voice.When I returned home to watch TV at night, the sound was always loud, and I didn’t even notice it.Until one family member asked her: “Such a loud voice, even elderly people with bad ears can’t bear it, can your ears eat it?” Later, after a doctor’s diagnosis during a physical examination, she was diagnosed with sensorineural hearing loss and hearing loss. The degree is already serious.
College student Xiaoyang suffered from insomnia due to excessive study pressure. She heard that listening to music can cure insomnia, so she wears headphones to listen to it for a while before going to bed every night. Often the music is still on, but she has fallen asleep. .The insomnia improved, but soon she found that she started to have tinnitus, and she was often unclear about what she heard, and asked others to say it many times.Later, she developed abnormal symptoms all over her body, often dizzy and headache, and even painful when she touched her ears, which seriously affected her study and life.After the doctor’s tuning fork examination and pure tone test, it was found that her hearing had dropped by 30 decibels from the normal level.
According to a scientific study from the United Kingdom, wearing headphones for a long time to listen to songs can lead to deafness 30 years in advance!
Listening to headphones on the subway hurts your ears the most
“In the environment of subways and buses, the volume level is not determined by hearing but by noise. Especially in the subway, it is a relatively closed environment, which will put a certain pressure on people’s ears, and then wear earphones tightly. When pressed tightly in the ear, the sound with strong intensity constantly hits the eardrum, which will cause damage to the hair cells.” An otolaryngologist expert told reporters this way.
The most used inner ear earplugs will increase the risk of hearing damage. Once it exceeds 80% of the maximum volume, the time listening to music should be shortened to less than 90 minutes.Studies have also shown that, for the listener, in-ear headphones and in-ear headphones are 5.5 decibels higher than ear cushion headphones.
In addition, experts also pointed out that the process of hearing loss is generally silent and gradual. In a short period of time, general damage may not affect communication with others temporarily, so it is difficult to arouse people’s vigilance, but then In a few years, people who like to use earphones will prematurely enter the people with hearing loss, and have a pair of ears that are prematurely aging.
Research also shows that human hearing is very delicate.Once the hair cells in the cochlea that feel the sound are damaged, it will cause a decline in language discrimination, that is to say, you can hear other people’s words, but you can’t understand the specific content.The number of such important cells is determined when a person is born, and the damage to each one will be reduced by one, which is irreversible.At present, the incidence of sudden deafness is very high among urban white-collar workers, and most of them are caused by over-use of headphones.
The volume does not exceed 60%, and continuous listening does not exceed 60 minutes
“People who often wear headphones to listen to music should master a ’60-60 principle’, which is also an internationally recognized method of protecting hearing. That is, when listening to music, the volume should not exceed 60% of the maximum volume, and the continuous listening time should not exceed 60%. XNUMX minutes. In this case, ears are relatively healthy.” Experts introduced some tips on ear protection in daily life to reporters.
In addition, try to listen to music in a quiet environment and try to avoid some noisy places.Experts believe that once the external environment becomes noisy, the output effect of the earphone will be interfered to different degrees; and in a quiet environment, the output sound effect of several earphones is almost the same.
Pay attention to when buying headphones.Choose some headphones that can block external noise to reduce the chance of increasing the volume of the Walkman due to environmental noise.Headphones are best to choose a head-mounted type, which has less damage to hearing than earphones.Because the earphones are directly plugged into the external auditory canal, the sound has no source, and it is all sent to the tympanic membrane. The sound is all received by the tympanic membrane, and the hearing damage is even greater.Generally speaking, to hear the same volume of music, the volume of earbuds is 7-9 decibels higher than that of headphones.
Early prevention of common ear diseases
The ear is an important sensory organ for humans, and it is also a relatively fragile human organ.In ordinary life, if you are not careful, there will be “conditions” in your ears, such as sudden deafness, otitis media, etc., which affect people’s normal life.To love ear protection, we must learn more about the prevention of some common ear diseases.
A sudden neurological deafness of unknown cause is currently believed to be caused by inner ear damage caused by factors such as vascular disease and viral infection.It is usually found that unilateral hearing loss is obvious after waking up, which may be accompanied by symptoms of tinnitus and dizziness.
Prevention: Pay attention to work and rest, pay attention to rest, avoid staying up late and mental stress.
Sensorineural hearing loss caused by degeneration of the inner ear and auditory nerve generally occurs after the age of 60 and is the main cause of deafness in the elderly.
Prevention: Actively treat hypertension and diabetes, delay nerve and microvascular disease.The treatment mainly depends on wearing hearing aids to improve hearing. In severe cases, cochlear implantation is feasible.
●Chronic suppurative otitis media
One of the main causes of conductive deafness is that the symptoms are repeated ear discharge, tympanic membrane perforation, and gradual hearing loss. Those with cholesteatoma can cause a variety of intracranial and extracranial complications.
Prevention: Try to avoid colds and ear water to reduce acute attacks; surgery should be performed as soon as possible to remove middle ear lesions, rebuild hearing, and prevent complications.
●Secretory Otitis Media
When the drainage channel of the middle ear-the Eustachian tube is blocked, fluid in the middle ear can occur, causing secretory otitis media.Secretory otitis media is a common cause of deafness in children, mainly manifested as hearing loss and ear diaphragm sensation.Long-term rhinitis, sinusitis and adenoid hypertrophy are common causes.
Prevention: remove the cause, actively treat nasal cavity and nasopharyngeal diseases; use drugs to promote the absorption and discharge of middle ear fluid; if necessary, tympanic membrane puncture or tympanostomy can remove middle ear fluid and improve middle ear ventilation.
Cerumen, commonly known as “earwax”, is a normal secretion from the external auditory canal of the human body. It has a protective effect on the skin of the external auditory canal. Excessive secretion or obstruction can cause the external auditory canal to become blocked, thereby affecting sound conduction.
Prevention: usually pay attention to avoid water in the ear canal; do not dig your ears to reduce damage and infection; if there are too many cerumen, you can clean the ear canal regularly.
Listen to songs and chew gum to protect your ears
Many young people like to listen to music while chewing gum. Although it may seem indecent, otolaryngologists believe that when listening to music with headphones, chewing gum can effectively protect their hearing.
Experts point out that chewing food while listening to music on headphones can relieve atmospheric pressure on the middle ear and the outside world.For example, many people feel ear pain during take-off and landing of an airplane, and perform actions that prompt the eustachian tube to open, such as swallowing saliva, eating, drinking, yawning, etc., and the symptoms will be relieved.
In addition, according to a study by the Taiwanese medical community, while wearing headphones to listen to music while chewing food, the sound wave pressure measured by the inner ear will be reduced by 1-3 decibels, thus achieving the effect of protecting the eardrum.
Anatomically, the anterior wall of the external auditory canal is the temporomandibular joint, and when a person is wearing headphones to listen to music, the temporomandibular joint will pull on the ears, causing the volume of the earbuds to leak into the ears, causing sound leakage. On the contrary, Can protect ears.
