Safety Guidelines
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: 204 Safety
X
Set the volume in a quiet environment
and select the lowest volume at which
you can hear adequately.
X
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.
X
Do not turn the volume up to block
out noisy surroundings. If you choose
to listen to your portable device in a
108
noisy environment, use noisecancelling
headphones to block out background
environmental noise.
X
Limit the amount of time you listen.
As the volume increases, less time is
required before your hearing could be
affected.
X
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.
X
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.
