Facts of Noise

Mumbai, India is the noisiest city in the world ……….. Central

Pollution Control Board (CPCB) Survey 2011

Deafness is on the rise in India

One in every 12 people is deaf ……… Indian Council of Medical

Research (ICMR)

“Noise” has become a major pollutant and great nuisance these days

Facts of Noise

Noise = Unwanted sound, now a public enemy

The environment gets contaminated which adversely affects health

and ill-effects are seen in living as well as non-living things

Sound = a form of energy giving the sensation of hearing produced

by longitudinal mechanical waves in matter

Decibel = unit for measuring noise intensity

Sources of Noise

INDUSTRIAL SOURCES

- Due to machines, big and small

NON-INDUSTRIAL SOURCES

- Loudspeakers - Construction work

- Automobile - Radio & Microphone

- Trains - Satellite launches

- Aircrafts - Mobiles PPRC/INDIA 04
