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 scientic 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
