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 cellular telephones, 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.
