Not long ago was "International Love Ears", and now a new "tired illness" - "Low-frequency deafness" rises quickly in people who are busy, stressed, and often staying up late. It is easy to "have a cold ear" Confusion, if you don't think it's an ear disease, don't treat it, it may lead to deafness that is difficult to treat!
Mainly attacking people with high pressure
From the case of the incidence of cases, there are pressures, busy work, excessive fatigue, frequent staying up late, and irregular life. Clinically, in recent years, sensorineural deafness has been in the white-collar workers with high pressure and busy work. The incidence rate is rising rapidly.
Why do stress and fatigue cause deafness?
The reason is that the inner ear region has the finest blood vessels in the whole blood vessels, and the blood vessels are the nutrient supply lines of the nerves. Excessive stress, excessive fatigue, emotional agitation, etc., can put the body in a state of stress, leading to autonomic dysfunction, resulting in microcirculation of the inner ear. Small arterial spasm, inner ear ischemia and hypoxia, insufficient supply of nutrients to the auditory nerve, resulting in partial damage to the inner ear, causing hearing loss.
"Walkman" became the culprits
Due to the invention of the Walkman, "music" has become the culprit of hearing damage. Because "high volume" and "long time" music will damage the hair cells of the inner ear, the nerve fibers, the neurons, and the microvessels that cause the inner ear. Oh, it hurts our hearing.
How big is "big volume"?
In general, sounds above 80 decibels can be detrimental to hearing. When someone hears the music from your headphones, or you can't hear the surrounding sound when you put on the headphones, it means the volume is too loud. You listen to music in the subway car, the background noise is as high as 85 to 100 decibels, to cover the background sound, the volume of the Walkman is often higher than 100 decibels.
How long is it "long time"?
In a high-noise environment, if it is only for a short period of time, the strained cells can be restored, calculated at 85 decibels, and the upper limit is 8 hours per day. If the limit is exceeded, the auditory cells do not have enough time to recover, and the accumulated time will be damaged.
The best treatment within a week
According to the severity of the deafness, mild deafness, moderate deafness... The total lack of hearing is severe, very severe deafness. The level of "low frequency deafness" is mild and moderate. The symptoms of lighter "low frequency deafness", rest Days, the symptoms will be relieved, so it is easy to mistakenly think that your ears are not sick. In addition, low-frequency deafness, in addition to "heavy female light men", there will be ear nausea, fullness, tinnitus, hearing loss and other symptoms, Some symptoms are similar to colds, etc., which can be mistaken for "cold and stuffy" and so on.
The timing of treatment of low frequency deafness is very important.
Although the otitis media caused by a cold can cause symptoms such as tinnitus, such tinnitus and deafness may be accompanied by pain, tympanic membrane bleeding and other symptoms, and there is a recent history of colds; if only simple hearing problems occur, such as suffocation and fullness Feelings, tinnitus, etc., without the symptoms of otitis media, you should beware of low-frequency deafness. Deafness is the best time for treatment within a week. The longer you drag, the worse the treatment effect, and some even lose hearing. Low-frequency deafness and genetics Genes are related, and some patients may recur after symptoms even after they are cured.
Don't listen to high-decibel music when you are tired
Everyone has pressure, the key is to learn to release pressure. Treatment, but also a two-pronged approach, while drug treatment, psychological counseling. Prevention, but also to prevent noise damage. Hearing has the characteristics of easy adaptation and fatigue. People are noisy In a strong sound environment, hearing will be reduced. If the hearing returns to normal after leaving the environment for 10~15 seconds, this is "hearing adaptation"; if hearing recovery takes several months or longer, or even completely recovers, it belongs to " Hearing fatigue".
If you listen to the sound of 85 decibels, listen for up to 8 hours; for every 3 decibels of sound, the time limit is reduced by multiples, that is, the time limit of 88 decibels is 4 hours, and the time limit of 91 decibels is 2 hours! The safety code for using the Walkman is: 60 %, 60 minutes, that is, set the volume to 60% of the maximum volume, no more than 60 minutes per day. If you continue to use the headphones, you should remove the headphones every half an hour, let the ears rest properly. On the bike, ride When walking, it is best not to listen to music with headphones. Even if you use it, you should control the volume. Do not use it for more than 1 hour each time. Do not listen to high-decibel music when you are tired, and avoid the superimposed damage of the ear "pressure plus noise"!
