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.
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.
