Light rain often has symptoms of earache recently. When I go to the hospital for a check, I know that it is a hearing loss. I only know when I asked for it because I had to go home from work every time I had to spend two hours riding a headphone to listen to music or watch a video.
There are many clinical cases like this. People can often see people wearing headphones to listen to music, watch videos, and play games on buses and subways. Many people do not realize that in these public places, the noise is relatively large, and many people unconsciously turn up the sound in order to be able to listen clearly. It takes an hour or two to get on and off the road. Vulnerable.
Noise-induced deafness has previously appeared in workers who are in a noisy environment. In recent years, people around them have become more and more entangled. Our inner ear has 18,000 cilia cells with a diameter of about 0.01 millimeter. They guard our hearing and provide a sound world for humans, but they are also very fragile and can't stand the long-term toss of noise and are easily damaged. Affect hearing.
Long-term continuous noise and short-term strong noise have the greatest impact on hearing. Xiaoqian belongs to the former. Deafness caused by transient strong noise is more common. Almost every two or three months, I encountered patients who suddenly went to deafness after going to karaoke bars and bars. When they learned that they were deaf after a night of revelry, they felt unbelievable. In addition, the sound of firecrackers, sounds of aircraft abatement, etc., are all transient strong noises, especially firecrackers. This is also the reason that the number of deaf patients has increased significantly during the Spring Festival each year.
Some people may also say that if you sing karaoke and listen to music with your headphones, why do people have good hearing and I will be deaf? This is because each person's hearing tolerance is different, and poor tolerance makes hearing disorders such as deafness and tinnitus prone to occur. Normal human hearing frequency ranges from 125 to 8000 Hz, and the language frequency ranges from 125 to 3,000 Hz. However, many hearing-impaired people can only hear sounds above 4-5 kilohertz, that is, face-to-face communication. Problems.
Modern life is inseparable from technology and entertainment, but it is recommended that everyone, whether singing or wearing headphones, be sure to “liberate†their ears for 10 minutes every 45-60 minutes. In noisy environments such as subways and buses, try not to wear headphones. If you want to wear headphones, the volume should not exceed 60% of the maximum volume. In addition, it is best to choose headphones, which are less harmful than earbuds.
