March 3 marks World Hearing Day. This year's theme is “Check your hearing!” Many experts and health organizations, including those who pay attention to the hearing-impaired (听力障碍), are working to help people realize the importance of protecting their hearing and avoid hearing loss.
When we talk about music, what kind of feelings does it bring? Excitement… and relaxation. But what if the music lasts for hours?
We interviewed a group of musicians based in Beijing during the weekend. They all said that hours of exposure to loud music can cause discomfort. One added that band members like to play at maximum volume (音量) and forget the harm that loud music can cause. The same thing not only occurs to musicians. It's also not rare for daily users since listening to loud music on loud sound equipment has become a part of modem life. According to the WHO, the practice has put more than a billion people around the world, aged 12-35, at risk of losing their hearing.
We also interviewed some headphone users in the street, and most of them said that they are not heavy users but admitted they use headphones for hours on the subway and in the office or home. It's easy for these people to gradually increase the volume without awareness, especially in a noisy environment. Often, headphone users fail to realize they're listening to audio at unsafe levels until serious hearing problems suddenly occur.
There are many reasons for hearing loss, including loud acoustic (听觉的) sources, drug abuse, and diseases. Experts suggest frequent medical checks and prevention measures.
Whether congenital (先天的) or acquired, loss of hearing is usuallyirreversible. “Once the hearing loss occurs, it's already too late to be changed back to what it was before,” said Yang Shiming, expert of the Chinese PLA General Hospital. “Early prevention, early identification and early treatment. If everyone could do these things, hearing loss and its harm could be kept to a minimum,” Yang said. Of course, this applies to every one of us.
