Noise may increasingly affect Americans at younger ages: analysis of the National Health and Nutrition Examination Surveythat the number of teens aged 12 to 19 with NIHL stemming from “recreational” noise grew from 11 percent in 1994 to 17 percent in 2006, while the percentage of teens listening to loud music through headphones grew over the test period from 19.8 percent to 34.8 percent.to intense sound such as explosion or jet engine.
What is meant by “loud?” Humans can begin to hear sound when it rises above zero decibels . The human ear perceives each increase of 10 decibels s to be twice as loud. If pleasant, soft sounds, such as a peaceful countryside measure only 20 decibels, quiet conversation, which measures 40 decibels, is four times as loud.
But just how much noise reaching our ears causes damage? The National Institute of Health maintains that sounds at or below 70 decibels are usually safe, while a few hours of exposure to 85 decibels noises will likely damage your hearing. A 100 decibels noise can damage your hearing after only 14 minutes, while 110 decibels sounds can cause damage after just two minutes and those above 130 decibels can immediately cause harm and actual pain.
