Important Safety Information 37
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 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.
