Do you like listening to music? Does all of the music bring happiness to you? Do you know some music is noise? What is noise? Noise is a loud or unwanted sound. It is also called noise pollution.

Where is noise from? Noise can be caused by many kinds of machines, such as motorcycles, planes, farm tractors and TVs. And, to some people, rock bands are also noise.

What happens to people who live near noisy machines or use them over a period of time? Doctors find that noise pollution can influence both our health and behavior. It can cause high stress levels, hearing loss, sleep problems, and other harmful effects.

Scientists use a unit(单位) of measure(测量) called a decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talk measures between 40 to 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the greatest hearing loss.

How do we reduce noise damage? Turn down your music player or wear ear muffs(耳罩) when you are working in a noisy environment. Ear muffs for human can protect against noise pollution.
