In our daily day life whatever we hear is sound. Some of them gives us pleasure some makes us irritate. So we can divide them into two part. The wanted sound and the unwanted sound. The unwanted sound is known as noise. But the definition of noise is difference from person to person. For example, the rock and dead metal sound can be enjoyable for some people so it’s not a noise for them. But a person who don’t like that sort of music can say that it’s a noise. So from this example we can say that a sound will consider as a noise or not is depended upon the listener’s persecution. But the fundamental is any unwanted unpleasant sound is consider as a noise.

How Sound Create

Sound is created by vibration. When we hit any object, its create some vibration and those vibration create sound and that sound come to our ear through making some wave in the air. But air is not the only media that can carry sound. Sound can also pass through water and some other object but sound can’t pass in airless area.

Effect of noise and noise pollution

Excessive noise is always harmful for us. There is some argument that what level of noise is consider as noise pollution but according to most of the specialist it is clear that sound level that cross 80 Decibel is consider as noise and noise pollution.

Noise prolusion have fetal effect in our life. If a person work in a noisy environment that can decrease his/her hearing level gradually. In the long run it can also cause permanent hear loss also. Excessive noise increase the blood pressure and also be a reason of heart attack. So we all should aware about this pollution.

 Pretension of noise pollution

Try not to create sound that make noise pollution is the main option to prevent noise pollution. If it’s not possible at list try to minimize those pollution is the main prevention way. In the work place like heavy weight manufacturing industry where noise pollution is almost impossible to avoided then active and passive noise cancelling procedure is the only way to protect our ears and hearing from sound pollution.

When we use any object the prevent the outside sound to come to our ear is known as passive noise canceling technique or procedure. There are different types of headphone are now available in the market that work as passive noise cancelling headphone.
