Noise pollution has become hazardous in many big cities of India like Delhi , Mumbai due to following factors-
With the increase in population, the volume of traffic and passenger has increased. This has led to more noise pollination.
More people have become prosperous in the cities. As a result of this, number of private vehicles such as cars have increased significantly. This has led to traffic jams during peak hours, i.e. in the morning and in the evening when people go and come from office. This has increased noise pollution on the roads.
Rapid industrialisation in and around the residential Colony has also increased noise pollution. Small and cottage industries are set up in the areas near the market.
The construction activities have increased to accommodate the ever increasing population in the big cities. These activities become hazardous as too much noise is created by them.
Religious activities, social functions, rallies, etc. create noise pollution particularly in the late hours of the day.
