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
