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.
