For years, parents have been telling kids to turn down the music. Now it's more important than ever for young people to hear the message.

Phones, iPads, and other devices deliver music that is clearer and louder than ever. That may sound like a good thing, but it is not so good for the health of the ears.

A new study confirms the danger. Scientists gave hearing tests to 170 students aged 11 to 17. The results showed that nearly 30% of the students had tinnitus(耳鸣), a condition that causes ringing in the ears. Ringing can be the result of a sudden loud noise. In that case, it is likely to go away. But constant ringing is a sign of trouble.

"These weren't kids who had just come from a rock concert," Dr Larry Roberts told Times For Kids. "We made sure they hadn't heard any loud sounds for a day or two."

Since the kids' tinnitus is a continuing condition, it is not likely to go away. Ongoing ringing in the ears is a sign of hearing loss. "There's no medical cure for tinnitus," warns Roberts. "These students will need hearing assistance earlier in life than others who don't have tinnitus."

Aside from the threat of future hearing loss，students with tinnitus also face immediate effects. They are more sensitive to loud sounds. They may have difficulty concentrating(集中精力)and sleeping.

What can you do to keep your hearing sharp? Follow the 60/60 rule. Set the volume under 60%. Don't use a device for more than 60 minutes a day.
