Avoid Potential Hearing Loss - Nokia 2605 Manual

■ 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 common-sense 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.
• Do not turn the volume up to block out noisy surroundings. If you choose
to listen to your portable device in a noisy environment, use noise-
canceling headphones to block out background environmental noise.
• Limit the amount of time you listen. As the volume increases, less time
is required before your hearing could be affected.
• Avoid using headphones after exposure to extremely loud noises such
as rock concerts that might cause temporary hearing loss. Temporary
hearing loss might cause unsafe volumes to sound normal.
• Do not listen at any volume that causes you discomfort. If you
experience ringing in your ears, hear muffled speech or experience any
temporary hearing difficulty after listening to your portable audio
device, discontinue use and consult your doctor.
