Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.

Noise adds more tension (紧张) to a society that already faces enough stress.
But noise is not a new problem. In ancient Rome, people complained so much about noise that government stopped chariots (四轮马车) from moving through the streets at night!
