　　How to protect your ears

　　You and your friends are leaving a concert on a Friday night.When you get outside，your ears are ringing.You have to shout to be heard.__1__So no harm done...right?

　　Not quite.Temporary buzzing may be easy to ignore，but repeated exposure to loud noise will eventually cause serious—and irreversible(无法治愈的)—hearing loss.A new study conducted by researchers at Brigham and Women's Hospital in Boston shows that one in five people between the ages of 12 and 19 are experiencing slight hearing loss，and one in 20 have mild hearing loss.__2__

　　But the good news is that there are plenty of ways you can protect your ears from further damage—and still listen to the music you love：

　　Ask around.Put your earbuds in or your headphones on，and then ask a friend next to you whether or not he or she can hear what you're listening to.__3__Turn it down.

　　Buy noise­canceling headphones.A pair of earbuds or headphones that fits comfortably will limit outside noise so that you can hear your music better at lower volumes.

　　Take breaks.__4__So when listening to music，take your headphones off for 15 or 20 minutes and let your ears enjoy the quiet.

　　__5__You can buy a cheap pair at any drugstore as an easy way to lower volume at concerts—or while playing or practicing your own music—without changing the quality of the sound.
