the most common cause of preventable hearing loss.
Some scientific research suggests that using portable
audio devices, such as portable music players and cellular
telephones, at high volume settings for long durations
may lead to permanent noise-induced hearing loss. This
includes the use of headphones (including headsets,
earbuds and Bluetooth
®
or other wireless devices).
Exposure to very loud sound has also been associated in
some studies with tinnitus (a ringing in the ear),
hypersensitivity to sound and distorted hearing. Individual
susceptibility to noise-induced hearing loss and other
potential hearing problems varies.
The amount of sound produced by a portable audio
device varies depending on the nature of the sound, the
device, the device settings and the headphones. You
should follow some commonsense recommendations
when using any portable audio device:
Set the volume in a quiet environment and select the
lowest volume at which you can hear adequately. When
using headphones, turn the volume down if you cannot
hear the people speaking near you or if the person sitting
next to you can hear what you are listening to. Do not turn
the volume up to block out noisy surroundings. If you
choose to listen to your portable device in a noisy
environment, use noise-cancelling headphones to block
out background environmental noise. Limit the amount of
time you listen. As the volume increases, less time is
required before your hearing could be affected. Avoid
using headphones after exposure to extremely loud
noises, such as rock concerts, that might cause
temporary hearing loss. Temporary hearing loss might
cause unsafe volumes to sound normal. Do not listen at
any volume that causes you discomfort. If you experience
ringing in your ears, hear muffled speech or experience
any temporary hearing difficulty after listening to your
portable audio device, discontinue use and consult your
doctor.
