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.
You should follow some commonsense recommendations when using any portable
audio device:
• Always turn the volume down before plugging the earphones into an audio source.
• Set the volume in a quiet environment and select the lowest volume at which you can hear
adequately.
• 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.
