The popularity of mobile communications and entertainment devices such as mobile phones and IPADs has provided a channel for time-consuming travel for office workers. However, because many people have to spend half an hour to more than one hour on the way to work, people on the bus and subway are everywhere for a long time. Dr. Dong Yuli, chief physician of the Otolaryngology Head and Neck Surgery Institute of the Guangdong Armed Police Corps Hospital, reminded that wearing a headset in a noisy environment is prone to hearing damage, and that older people are more likely to have hearing loss, but wearing headphones for a long time will accelerate this hearing impairment.
Long-term noise stimulation can lead to progressive hearing loss
According to statistics, more than 30% of hearing impairments are related to hearing damage caused by noise. When people are in a noise environment for a long time, they will not only suffer from hearing loss, but also suffer from earache, tinnitus, dizziness, and headaches. “Many people who work in a noisy environment, such as factory workers, traffic commanders, bar DJs, etc. must wear earplugs, earmuffs and other protective tools to protect their hearing while working, but many people still think that they should listen to the bus or subway. The damage to hearing from music and watching TV dramas does not appear to be the case of the aforementioned practitioners, and it is considered that hearing impairments are not significant; in fact, this is not necessarily the case.†Dong Yuli said. He said that in urban areas, the sound of road environment will generally reach 60 decibels or more. When a person wants to hear the sound produced by a headset, he or she will naturally adjust the volume of the headset to more than 60 dB; when the sound exceeds 90 dB, the person’s hearing It has already been severely affected, but this effect is not immediately felt by human beings. In the long-term, it will progressively “erode†hearing.
With headphones: sound volume as low as possible, no more than an hour
Dong Yuli said that the best way to prevent hearing loss is not to wear headphones, but when it's necessary to do so, it is best to turn down the volume of the headphones. “The volume should be controlled within 50% of the range, noisy. In the environment, even when 50% of the volume is inaudible, do not listen to it.†At the same time, Dong Yuli said that when wearing headphones feel dizzy, earache, it should be immediately removed headphones, can not think that for a while will be good, “ Because of this, hearing loss has already begun."
