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.
