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
