On the first day of the new year, Mr. Liu, who lived in Tianhe, was shaken in his ears when setting off firecrackers, and his left ear could not hear the sound, as if his ears were blocked by something. In anxiety, he directly picked up the ear spoon I dug my ears, and as a result, my left ear was painful, but I still couldn t hear the sound, so I had to help the doctor. During the examination, the doctor found that there was a blood clot on Mr. Liu s left ear canal. After cleaning the blood vessels, he found that Mr. Liu s eardrum had been perforated. Due to Mr. Liu s improper handling of ear-pick spoons, he has caused secondary damage to his ears. The doctor prescribed him anti-infection drugs and reminded him to avoid water in the ears within one month. The tympanic membrane can slowly heal itself.
In response to this, the doctor said that the firecracker explosion is an instantaneous contact with a huge sound, which may cause damage to the tympanic membrane and damage to cochlear hair cells. In this case, you should go to the hospital immediately, instead of picking your own ears, causing further injury.
March 3rd is the 16th Ear-Love Day in China, and the theme of this year is Safe Ears and Protect Your Hearing. Hearing damage due to noise is common worldwide and can be prevented and should be taken seriously.
Studies show that noise is one of the important causes of hearing disabilities. Many young people like to release stress in noisy entertainment places, such as bars, KTV, etc. If they are in such an environment for a long time, it can easily cause hearing damage. Some people like to listen to music with headphones at all times, and often turn the volume up so that they are immersed in the world of music.
In the past, people had a recorder and a walkman when they listened to music. Later, they had MP3 and MP4. Now the computer and mobile phone in their home can easily download and listen to music at any time. Old Chinese medicine reminds you that when listening to music, you must pay attention to both the listening time and the sound intensity.
The sound exceeds 60 decibels, and continuous listening for more than 3 hours may cause noise-induced hearing loss and suffer from noise-induced deafness. The doctor said that this is worthy of attention from friends who like music. Earphones should pay more attention and learn Ears relax and rest quietly. In the clinic, there are many young patients with noise-induced hearing loss, and they have also encountered children with noise-induced hearing loss. The doctor asked the reason and learned that it was caused by the loud sound of the TV and computer in the home.
Check your hearing before purchasing hearing aids and perform fitting based on the degree of hearing loss, otherwise you may deaf more and more. The scientific selection of hearing aids should include hearing inspection, hearing aid selection, computer debugging of hearing aids, etc., which must be operated by professional fitters at professional fitting points. In fact, fitting hearing aids is the same as wearing glasses. Improper glasses can cause vision loss. Hearing aids are purchased in stores or online malls. The salesperson is only responsible for sales, and does not understand professional fitting. Of course, users wear discounts when wearing them.
Wearing while wearing the hearing aid, pay attention to some issues such as ear comfort, echo and noise. First of all, hearing aids should be comfortable and painless, and if there is pain, you should contact your home technologist. Secondly, there should be no echoes or loud sounds. Once these conditions appear, it indicates that the patient s hearing aid needs to be adjusted. Finally, avoid noise to avoid discomfort. If the patient feels the noise is too loud and the hearing aid gets wet, you need to go to the hearing aid fitting center for debugging and dry maintenance immediately.
Awareness of preventing noise-induced hearing loss. Hearing damage caused by noise can be divided into two types: acute sound damage and chronic sound damage. The former is mainly caused by the instantaneous exposure of high-intensity impulse noise. It is more common after detonation and is also called deafness. Acute acoustic injury can be treated as sudden deafness, while chronic acoustic injury is hearing damage caused by long-term continuous strong noise stimulation, which is difficult to cure and can only be prevented. Therefore, it is important to raise the awareness that noise is harmful to hearing.
Be careful not to stay in a noisy entertainment environment for a long time. You can reduce the intensity of music and microphone when singing to KTV, and control the volume and time when listening to music with headphones. If you live in a noisy environment, you can install some sound insulation materials in your home to reduce noise pollution.
For friends who have been in a noisy environment for a long time because of work needs, experts recommend a hearing check for 3-6 months, early detection of hearing damage, and proper treatment.
