"...a typical person can safely listen to an iPod for 4.6 hours per day at 70% volume."
"...knowing the levels one is listening to music at, and for how long
is extremely important."

Use Responsibly
Do not use headphones when it's unsafe to do so – while operating a vehicle,
crossing streets, or during any activity or in an environment where your full
attention to your surroundings is required.
It's dangerous to drive while wearing headphones, and in many places,
illegal because it decreases your chances of hearing life-saving sounds
outside of your vehicle, such as another car's horn and emergency vehicle sirens.
Please avoid wearing your headphones while driving. Use one of Monster's
FM transmitters to listen to your mobile media devices instead.
Learn how to establish a safe listening level and review other important
safety guidelines from the Consumer Electronics Association at www.ce.org.
