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 scientic 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.
• 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.
