Caution:
Avoid potential hearing
loss.
Prolonged exposure to loud
sounds (including music) is
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.
