Avoid Potential Hearing Loss
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).

SAFETY SAFETY
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.
