The MP3 Generation: At Risk for Hearing Loss?
Experts discuss the possible risk to hearing from listening to MP3s for long periods of time.
Hearing Loss Goes Unnoticed
Denying the danger of noise-induced hearing loss would not be so easy if
loud music made the ears bleed, but the early symptoms tend to come on
"People may notice that voices sound muffled, and that they have a
reduced ability to follow a conversation in a noisy environment such as a
restaurant or a party," Andy Vermiglio, CCC-A, FAAA, a research audiologist
at the House Ear Institute in Los Angeles, tells WebMD.
"They might hear ringing in their ears. In its worst form, the ringing
can get so loud that it interferes with sleep."
While a routine hearing test administered by a doctor can reveal mild
hearing loss, the problem may become advanced before people realize they're
having serious difficulty hearing.
Hearing loss, which becomes more common with age, is creeping farther down
the age spectrum.
Kids With Old Ears
An article in the journal Pediatrics estimated that 12.5% of
children aged 6 to 19 -- about 5.2 million -- have noise-induced hearing
"Our own research shows that 16% of 6- to 19-year-olds have early signs
of hearing loss at the range most readily damaged by loud sounds," says
William Martin, PhD, of the Oregon Health and Science University Tinnitus
Clinic in Portland.
Because adolescents are so resistant to warnings about loud music, Martin is
trying to raise awareness among younger children. He is co-director of the
Dangerous Decibels Project, which, in conjunction with the Oregon Museum of
Science and Industry in Portland, has developed a program designed to train
children, parents, and teachers about the threat of noise-induced hearing loss.
It stresses the three most practical ways to deal with loud noise: turn it
down, walk away, or protect your ears.
But education merely raises awareness of the problem. As with the epidemic
of obesity among the young, hearing loss will end only when young people
themselves recognize the dangers and change their behavior.
"People have to use personal stereo systems wisely or they will rapidly
accelerate the aging of their ears," says Martin. "You can't toughen
your ears by listening. Some people think you can. But if it's loud enough for
long enough, you're going to cause permanent damage to your hearing."
