Causes Of Noise Pollution
• Traffic noise is the main source of noise pollution caused in urban areas. With the ever-increasing number of vehicles on road, the sound caused by the cars and exhaust system of autos, trucks, buses and motorcycles is the chief reason for noise pollution.
• With the low flying military aircrafts soaring over the national parks, wasteland and other vacant areas, the level of noise pollution has drastically increased in these previously unaffected zones.
• People living beside railway stations put up with a lot of noise from locomotive engines, horns and whistles and switching and shunting operation in rail yards. This is one of the major sources of noise pollution.
• To meet the demands of the basic necessity of living, the construction of buildings, highways and city streets causes a lot of noise. Pneumatic hammers, air compressors, bulldozers, loaders, dump trucks and pavement breakers are the major sources of noise pollution in construction sites.
• Though not a prime reason, industrial noise adds to the noise pollution. Machinery, motors and compressors used in the industries create a lot of noise which adds to the already detrimental state of noise pollution.
• Plumbing, boilers, generators, air conditioners and fans create a lot of noise in the buildings and add to the prevailing noise pollution.
• Household equipments, such as vacuum cleaners, mixers and some kitchen appliances are noisemakers of the house. Though they do not cause too much of problem, their effect cannot be neglected.

Noise pollution is said to occur when sound becomes displeasing to the ear and disrupts normal human and animal activity and stability.
The maximum permissible level of noise is exposure to 85dB noise for not more than 8 hours. This limit is applicable to factories and construction sites. Permissible limits for commercial areas are 65dB for the day and 55dB during the night. For residential areas, noise should not exceed 55dB during day and 45dB during night.
Some of the common sources (agents) of noise pollution are:
  • Transportation and vehicles
  • Aircraft noise
  • Proximity of industrial and residential areas (poor planning)
  • Factory machinery
  • Construction work
  • Loud music
  • Electric appliances (blender, electricity generator)
  • People
Noise pollution has many effects on human health. Often old people experience noise induced loss of hearing. It also causes stress and anxiety. In natural ecosystems, it greatly distresses animals which reduces their breeding capacity. It may also cause a disruption in the animal's way of navigating or locating mates. High noise levels may cause the animals to move away from these areas which leads to a decrease in their area of habitat.

One of the main reasons for noise pollution is the traffic of the cars they all honking which increases the dB from 20000hz(it is the normal range which a human ear can hear) if there is a rise from 20000 dB it can cause damage to the ears.
