players and cell phones, 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
potential hearing problem varies. Additionally,
the amount of sound produced by a portable
audio device varies depending on the nature of
the sound, the device settings, and the
headphones that are used. As a result, there is
no single volume setting that is appropriate for
everyone or for every combination of sound,
settings, and equipment.
You should follow some common sense
recommendations when using any portable
audio device:
• Always turn the volume down before plugging the
earphones into an audio source.
• Set the volume in a quiet environment and select
the lowest volume at which you can hear
adequately.
• Be aware that you can adapt to higher volume
settings over time, not realizing that the higher
volume may be harmful to your hearing.
• 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. By blocking background environment noise,
noise cancelling headphones should allow you to
hear the music at lower volumes than when using
earbuds.
• Limit the amount of time you listen. As the volume
increases, less time is required before you 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.
