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:
