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:
• 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.
