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.
• 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-cancelling
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.
