PREVENTION OF HEARING LOSS

Caution: Avoid potential hearing loss

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 other potential hearing problems varies.

The amount of sound produced by a portable audio device varies

depending on the nature of the sound, the device, the device settings and

the headphones. You should follow some commonsense recommendations

when using any portable audio device:

• 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.

• 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.

• Limit the amount of time you listen. As the volume increases, less

time is required before your hearing could be affected.
