SAFETY AVOID POTENTIAL HEARING LOSS
CAUTION:
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). 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
