Any artificial or natural addition of substances to our ecosystem which causes imbalance in our biosphere is called pollution. Such substances that cause pollution are called pollutants. And noise or sound has become a dreaded pollutant today.

Noise pollution is as dangerous and widespread as the air or water pollution. Constant exposure to loud noise causes various neurological problems, sleeplessness, indigestion and cardiovascular problems. Our ears are very sensitive organs. They remain always wide open to sound. So there is a continuons one laugh of noise in our ears when we are awake as wella when we are asleep. Such onslaught is more heinous in cities and industrial areas. Constant exposure to such harsh attacks on the ear. The drum has left many deaf to finer, subther and soft sounds.

The relative loudness of sound is measured in decibels. The lowest audible sound is one decibel. Human ears can tolerate sound upto 60 to 70 decibels. Sound at more or near 100 decibel can create permanent deafness.

Thé constant noise produced by trains, traffic, factories, public address systems, and hifi music in towns and cities make life uncomfortable. Even the silence of nights are shattered brutally by the sharp shrills of factory sirens, air-horns of vehicles and loud sounds emanating from loudspeakers used by orchestra groups or in some religious function.

Noise of loudspeakers, noise of marriage processions, noise of religious functions, noise of rallies. The deafening sound of landing and taking-off of aeroplanes and helicopters adversely affects the senior citizens, infants as well as students. An old man cannot enjoy his rest, a student cannot concentrate in his studies when sound is beyond 80 decibel. Now-a-days in any street we get a 120 decibel sound. Even in public buses some uncouth conductors or drivers play hifi music throwing all the rules of transport away to the Wind. Such playing of music in buses causes discomfort to a majority of passengers. As a result they feel dizzy and exhausted when they end their journey.

Public awareness about the ill effects of sound is the prime need in our fight against noise pollution. Students in schools and colleges must know how sound pollution is affecting them adversely

The laws formulated by the government to check pollution cannot come out successful by itself. It will come to an end when we will open our soft voice against the harsh sound caused by others. We need to be brave to do it.
