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.
●
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,
