indicates that using a wireless phone while driving degrades

a driver's performance, whether it is a hands-free or hand-

held wireless phone. NHTSA advises that the "safest course

of action is to refrain from using a cell phone while driving."

NHTSA's policy on "Cell Phone Use While Driving," as well as

Frequently Asked Questions on the subject, are available at

www.nhtsa.gov (click on "Traffic Safety" then on "Drowsy and

Distracted Driving").

For your well-being and the well-being of those around you, you

should consider turning your phone off and allowing calls to go

to voice mail while you are driving.

If you choose to use your wireless phone while driving, several

jurisdictions have adopted "hands-free" and other restrictions

on the use of wireless devices while driving. It is your

responsibility to know and to comply with the law in your area.

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

back ground environmental noise.

• Limit the amount of time you listen. As the volume

increases, less time is required before your 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.

• Do not listen at any volume that causes you discomfort. If

you experience ringing in your ears, hear muffled speech or

experience any temporary hearing difficulty after listening

to your portable audio device, discontinue use and consult

your doctor.
