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 listening to.
