World Health Organization has cautioned about 1.1 billion teenagers and adults the risk of a loss of hearing because of high-risks of the usage of audio devices, smart-phones, outrageous levels of noises at nightclubs, bars and various other events.
According to the WHO people should not be using audio devices for more than an hour per day.
The data analyzed by WHO from average and high disposable income countries suggests that almost 50% of teenagers and adults of aged from 12 to 35 are exposed to hazardous levels of sound due to personal audio devices and about 40% being exposed to harmful level of sounds emitting from clubs and other noisy events with loud music.
Sound level is considered unsafe when there is more than 85dB (decibles) for 8 hours or 100db for 15 minutes.
Dr Etienne Krug, WHO Director for the Department for Management of Non-communicable Diseases, said As they go about their daily lives doing what they enjoy, more and more young people are placing themselves at risk of hearing loss.
Taking simple preventive actions will allow people to continue to enjoy themselves without putting their hearing at risk, added Dr. Krug.
According to the WHO the highest acceptable level of exposure to sound at work is 85 dB for about 8 hours a day at max.
There should be a considerable amount of reduction to the duration of exposure with high levels of sounds in places like bars, clubs and other events with loud music on. Sound levels of 100dB are not exactly safe for more than the duration of 15 minutes.
It has been advised by the WHO that individuals can protect their hearing by keeping down the volume of their audio devices and putting on ear plugs when going to loud places along with the usage of well-fitted noise cancellation earphones.
Another way to be safe is restrict the amount of time spent in loud activities and limiting the regular usage of audio devices to less an hour a day.
An upside of smartphones is that they warn the level of safe listening level on a regular interval so people should follow that.
March 3rd is the International Ear Care Day and to highlight this day WHO has taken an initiation to draw attention to the risks of unsafe listening and promoting better practices by launching Make Listening Safe initiative.
WHO is collaborating with its partners as well as advocating governments to put more attention to this issue by taking a strong stand on this matter of grave concern to prevent the youth all over the world to be safe and sound.
