Answer: The unit by which the loudness of sound is measured is called a decibel. According to the UN. the normal tolerances limit of sound is 45 decibels. When a sound exceeds this limit, it is sharp and harsh. It is called ‘noise’. A noisy place means the place is polluted by sound. The causes of sound pollution are many. For example, use of loudspeakers and cassette players at high volume, shouting slogans at processions or political and religious occasions, playing radio and TV at top volume, staging band shows as above all the use of hydraulic horns by trucks and buses. Sound pollution is harmful to our health. It causes lack of concentration, annoyance, irritability, the rise in blood pressure, an increase of the normal rate of heartbeat and gradual deafness. To get rid of this problem we have to pass strict laws against the sources of noise. Then public awareness should be developed through mass media. Everyone must cultivate the virtue of quietness in personal and social life.
