AVOID POTENTIAL
HEARING LOSS.
139
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 por-
table 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 head-
sets, 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.
