Listening to loud music on earphones harmful

Listening to loud music with earphones might be entertaining, but listening to it for more than 90 minutes a day can damage your hearing.Researchers from the Children's Hospital of Boston and faculty of Harvard Medical School studied 100 doctoral students and found that people who listened to music at 80 percent of volume capacity, at which point the sound is considered loud, should stick to under 90 minutes a day. If a person exceeds that on one particular day and not use their headphones for the rest of the week, they're at no higher risk. This relates to someone who's exceeding 80 percent for 90 minutes day after day, month after month, for years.The study also found no problems for people who listened to music at 10 percent to 50 percent of maximum volume for extended periods. It found, however, that anyone who listened at 100 percent for more than five minutes faced the risk of hearing loss. The finding applies to children and adults. The scientists found no differences in sound levels between brands of digital music players or between the genres of music tested which ranged from rock, R&B, country, to dance.People who consistently listen to high levels of volume don't realise that hearing loss can take up to 10 years to show up. Teenagers going to be 23, 24, 25-year-old have a measurable noise-induced hearing loss and now have another 60-something years to live with his hearing, which is only going to get worse.Another study, by researchers from the Pennsylvania's College of Optometry's School of Audiology, found in-ear earphones, which broadcast sound directly into the ears, are no more dangerous than headphones that are placed over the ears.
