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 is no single volume setting that is appropriate for everyone or for every combination of sound, settings, and equipment. You should follow some common sense recommendations when using any portable audio device: • Always turn the volume down before plugging the earphones into an audio source. 110 • Set the volume in a quiet environment and select the lowest volume at which you can hear adequately. • Be aware that you can adapt to higher volume settings over time, not realizing that the higher volume may be harmful to your hearing. • When using headphones, turn the volume down if you cannot hear the people speaking near you or if the person sitting next to you can hear what you are listening to. • Do not turn the volume up to block out noisy surroundings. If you choose to listen to your portable device in a noisy environment, use noise-cancelling headphones to block out background environmental noise. By blocking background environment noise, noise cancelling headphones should allow you to hear the music at lower volumes than when using earbuds. • Limit the amount of time you listen. As the volume increases, less time is required before you hearing could be affected. • Avoid using headphones after exposure to extremely loud noises, such as rock concerts, that might cause temporary hearing loss. Temporary hearing loss might cause unsafe volumes to sound normal.

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

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

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.
You should follow some common sense
recommendations when using any portable

•
Always turn the volume down before plugging the
