प्रश्न
How has noise pollution become a serious problem in recent years in India? Explain.
उत्तर
Noise has become a serious concern only in recent years due to a variety of technological innovations.
- The biggest nuisance is the noise produced by traffic, because its intensity and nature depend upon factors, such as the type of aircraft, vehicle, train and the condition of road, as well as that of vehicle (in case of automobiles).
- In sea traffic, the noise pollution is confined to the harbour due to loading and unloading activities being carried.
- Industries cause noise pollution but with varying intensity depending upon the type of industry.
- Ocean noise is due to the vast increase in global shipping trade, the number of ships plying the oceans and higher speed of vessels.

The main sources of noise pollution are various factories, mechanized construction and demolition Works, automobiles and aircraft, etc. There may be added periodical but polluting noise from sirens, loudspeakers used in various festivals, programmes associated with community activities. The level of steady noise is measured by sound level expressed in terms of decibels (dB). Of all these sources, the biggest nuisance is the noise produced by traffic, because its intensity and nature depend upon factors, such as the type of aircraft, vehicle, train and the condition of road, as well as, that of vehicle (in case of automobiles). In sea traffic, the noise pollution is confined to the harbour due to loading and unloading activities being carried. Industries cause noise pollution but with varying intensity depending upon the type of industry. Noise pollution is location specific and its intensity declines with increase in distance from the source' of pollution, i.e. industrial areas, arteries of transportation, airport, etc. Noise Pollution is hazardous in many metropolitan and big cities in India. |
- Explain the meaning of noise pollution.
- Why is noise pollution hazardous in metropolitan cities in India?
- "Noise pollution is location specific." Explain with argument.
