Responsible Listening
Caution! Avoid potential hearing loss
.
Damage to hearing occurs when a person is exposed to loud
sounds over time. The risk of hearing loss increases as
sound is played louder and for longer durations.
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 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.
