Under the threat of hearing loss up to 30 years of age, there is more than one billion adolescents. The main culprit for this trend are the headphones, or rather their improper use. Already, WHO statistics nearly fifty million people to 35 years old, lose their hearing. Every year, this percentage is growing more and more.
To start Dr. Etienne Krug offers to teach teenagers case, music on headphones less than an hour a day. It is important to talk about this issue in school, yet can make a difference. The fact that a person’s hearing over time to get used to loud noises, perceiving them as a norm. Once hearing adapts to the loud sounds of headphones, the user raises the bar for volume and over time this leads to the fact that a person does not perceive the softest sounds.
Scientists have made a graph showing how long it is safe to listen to music and at what volume .
A valid residence time in the headphones:
- 15-30dB – unlimited
- 30-50dB – 20h. 6h. 3-4ch.
- 50-80dB – 4h. 2h. 30 minutes.
- 80-100dB – 50-60min. 10min. 5 min.
In order to understand about the ratio of decibels to the sound daily, you can look at the infographic.
On the recommendation of WHO experts, the use of headphones should be limited. Considered safe listening no more than an hour on the volume to 60%. Knowing the psychology of adolescents, the WHO does not expect that they will take the recommendation seriously, so it was decided to reduce the force level of input sound directly to manufacturers of headphones. Previously, there was an attempt to influence the manufacturers, after which many players were equipped with volume limiter, but few people used them. WHO is now trying to make a crucial step – to ban the production of headphones, the sound level exceeds the safe.
Also, WHO proposes to prohibit loud music in public places, and to oblige the owners to buy earplugs that will be issued free of charge to visitors. How it will be hygienically still unknown, and we go to the cafe does not shut up, so that such services can not be a success. The most interesting thing that earplugs will offer and the clubs, the response to such innovation youth can be predicted accurately.
What headphones safer for hearing
Many argue that in-ear headphones, tightly closing the hearing aid – more dangerous, because they create strong vibration membrane. In part they are right, but in such a clear sound with headphones and you can not hear outside noise, so people rarely increases the volume above the allowed rate.
Headphones open type, do not create such pressure on the hearing aid, but miss the noise from the street or public transport. A man with such headphones forced all the time listening to music at maximum volume, which brings even greater harm than the ear headphones.
If you go back to the statistics, only twenty years ago, poor hearing complained only the elderly 70 years old, Now these patients are not more than 40 years.
