You including teenagers who like to play music out loud using iPods or other MP3 player?If so, you should immediately stop the habit because a study in the United States (U.S.), which is published by the Journal Of The American Medical Association reveals that the number of teenagers who have a hearing loss has increased by almost a third in the last 15 years.
The report quoted Reuters Life! It departed from a study comparing national surveys since the early 1990s until the mid-2000s and involved several thousand teenagers from ages 12 to 19 year.In the first survey as many as 15 percent of teenagers known to decrease as much as some level of hearing ability by a few trained staff. But about 15 years later that number increased by almost a third, approaching the value of 20 percent or in other words afflicts one in five adolescents in the U.S..
“That equals the number of adolescents in each class will have a hearing problem,” said Dr. Josef Shargorodsky of Brigham and Women’s Hospital, Boston, USA.”The teenagers underestimate no matter how hard the sounds they hear. Often an individual does not realize it but even the slightest hearing loss will make a difference in language development and learning process,” continued Shargorodsky.
The study found that most cases of hearing loss that afflicts one ear but the disruption it will get worse.For while the disturbance was indeed seem trivial, but one of 20 teenagers turned out to have trouble pronouncing words, increased by 50 percent since the first survey was held.
Shargorodsky admitted surprise with the discovery. According to an appropriate medical treatment for ear infections, as one of the main causes of hearing damage, theoretically should be able to reduce the number of people with it.But the researchers were not able to determine only one devices such as iPods as the cause of the problem.
They assess the reasons for the increasing number of teenagers who suffer from hearing loss is unclear, because when asked about the sources of noise, such as from a firearm, in the workplace, or place of recreation, there is no answer to indicate a significant change.But for some people Shargorodsky not necessarily assess the music they listen to the music player such as ‘MP3 player’ for example, as noise.
“We already know that it is very difficult to ask the people of that age group as they received about the noise. They despised him,” said Shargorodsky.”Some risk factors, such as loud noise received when listening to music, probably an important factor for adolescents,” the sound of one statement in the report.
Alison Grimes, who runs clinics at the Audiology Ronal Reagan-UCLA Medical Center in Los Angeles, USA said that while the devices were not necessarily the music cause hearing damage, but the idea to turn down the music volume and reduce the use of devices like the iPhone is very good.
