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.
