Ans. Sources of Noise Pollution: -
Noise can come from many places. Let us see a few good
sources:
Noise and nuisance
Household sources: -
Gadgets like food mixer, grinder,
vacuum cleaner, washing machine and dryer, cooler, air conditioners, can be
very noisy and injurious to health. Others include loud speakers of sound systems and TVs, ipods and ear phones.
Another example may be your neighbor’s dog barking all night everyday at every
shadow it sees, disturbing everyone else in the apartment.
Noise and nuisance
Social events: -
Places of worship, discos and gigs,
parties and other social events also create a lot of noise for the people
living in that area. In many market areas, people sell with loud speakers,
others shout out offers and try to get customers to buy their goods. It is
important to note that why these events are not often, they can be called
'Nuisance' rather than noise pollution.
Noise and nuisance
Commercial and industrial activities: -
Printing presses, manufacturing
industries, construction sites, contribute to noise pollutions in large cities.
In many industries, it is a requirement that people always wear earplugs to
minimize their exposure to heavy noise. People who work with lawn mowers,
tractors and noisy equipment are also required to wear noise-proof gadgets.
Noise and
nuisanceTransportation: -
Think of aero planes flying over houses close to busy
airports like Heathrow (London) or Ohare (Chicago), over ground and underground
trains, vehicles on road—these are constantly making a lot of noise and people
always struggle to cope with them.
