7.6 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:
