Noise Pollution
What is Noise Pollution? Sound is essential to our daily lives, but noise is not. Noise is an unwanted sound, or a sound which produces unpleasant effects. Not all noise can be called noise pollution. If it does not happen regularly, it may be termed as 'Nuisance‘.
Sources of noise pollution Household sources Transportation Social events Commercial and industrial activities
The effects of Noise Pollution 1. 2. 3. 4. 5. Hearing Problems Health Issues Sleeping Disorders Cardiovascular Issues Trouble Communicating
It effects animals, too. Scientists believe that it’s not only humans who are affected. Example: ◦ Water animals are subjected to noise by submarines and big ships ◦ chain-saw operations by timber companies also create extreme noise to animals in the forests
Noise pollution in our school We measured noise multiple times in our school using sound level meter We measured sound in three places. This is the average number of decibels: ◦ School canteen = 91 d. B ◦ School Hall = 87 d. B ◦ The classrooms near the road = 88 d. B Some are above the recommended decibels a human should be exposed to 8 h a day.
What we did to prevent it We padded the doors so they would be sound proof in the music and history classrooms In the other classrooms we hanged signs that say to keep it down.
How to prevent noise? Construction of soundproof rooms for noisy machines in industrial and manufacturing installations. Use of horns with jarring sounds, motorbikes with damaged exhaust pipes, noisy trucks are to be banned. Airports, bus and transport terminals and railway stations should be sighted far from living places.
