【原文】

The sense of sound is one of our most important means of knowing what is going on around

us. Sound has a wasted product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets and better.

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—the crashing, squeaking, banging, hammering of people—is no joke. It is a threat that should be looked at carefully. Sound is measured in units called ―decibels‖. At a level of 140 decibels people feel pain in their ears.

Automobiles, trucks, buses, motorcycles, airplanes, boats, factories, bands—all these things

make noise. They bother not only our ears, but our minds and bodies as well. There is a saying about it being so noisy that you can‘t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don‘t we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension to society that already faces enough stress. But noise is not a new problem. In ancient Rome, people complained so much about noise

Noise can be separated into a few general groups. The following examples are taken from

Occupational noise—Factory workers who always hear noise have poorer hearing than other

groups.

Aircraft noise—Around airports or on air routes the noise of airplanes taking off and landing

causes the greatest complaints.

Traffic noise—Away from the noise of planes, traffic sounds break in on our peace and quiet.

Trucks and motorcycles cause the most problems.
