Caution! Avoid Potential Hearing Loss
Prolonged exposure to loud sounds (including
music) is a 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.
