Health and Safety Information 39
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 potential
hearing problem varies. Additionally, the
amount of sound produced by a portable
audio device varies depending on the
nature of the sound, the device settings,
and the headphones that are used. As a
result, there is no single volume setting
that is appropriate for everyone or for
every combination of sound, settings,
and equipment.
You should follow some common sense
recommendations when using any
portable audio device:
• Always turn the volume down before
plugging the earphones into an audio
source.
• Set the volume in a quiet environment and
select the lowest volume at which you can
hear adequately.
• Be aware that you can adapt to higher
volume settings over time, not realizing
that the higher volume may be harmful to
your hearing.
