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
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.
