Timing belt on 2005 Hyundai Sonata

Just bought this car. Now I learn that I've got to worry about a timing belt at 60,000. Why? I never had to replace a belt/chain on all of my previous American cars. Is it because it's a belt? Why didn't Hyundai use a chain?

all imports used a belt because of noise. if you neglect to change it and it breaks, you will be looking at a bill of about 1800-2000.

Noise? Could you please go into that in a little more detail? Noise? To me, that's ludicrous. Why are they concerned with noise and American car makers aren't?
Thanks, Roy. I'm in Palmetto, Florida.
