Environment | 5-12 yrs | Reading Pod

What is noise pollution?

Noise is defined as unwanted sound. Pollution – an excessive and annoying degree of noise in a particular area. Examples – traffic or aeroplane engines.

How is it measured?

A decibel is used for the measurement of noise. Examples – 20 db is a whisper. 40 db is a quiet office. 60 db is normal conversation. 80 db is the level at which it starts becoming uncomfortable to the ear.

What are the types of noise pollution?

This broadly falls under 2 categories – natural and man-made.

What comes under Natural noise?

Noise or sound from the wind, rain, storms, trees, birds, animals are all natural sounds.

What are man-made sounds?

Noise or sounds from engines, construction, traffic, blaring speakers are all man-made sounds.

Am I adding to noise pollution?

  • Do you listen to your television so loudly that your neighbours can hear?
  • Do you play your music system at home or in the car for people outside to hear?
  • At festivals like Diwali are you the one who lights the noisy bombs and fiery crackers at night?
  • Be aware of the level at which you speak at home. Try a fun game of sign language, then whispers then normal conversation and then shouting to see the different effects of noise on people around you.
  • Observe sound around you when you are out with your parents. While driving by a hospital see if people take care and not honk and blow the horn or do they ignore that and honk away? Is that appropriate?

What do you think?

  • You could do your bit and make sure your mom or dad do not honk while going by a hospital.
  • Not only is noise distracting but it can create stress and health issues. Find out more about this for yourself and make an activity or project around it.

Conduct a noise quiz.

Ask adults you know how sound impacts them. Does it disturb them? What happens to their concentration levels when it is noisy?

Pick a comfortable volume at which you can listen to music and watch the television without disturbing others.

Email us and let us know what you observed. Come up with a cool idea or activity around noise pollution and tell us what you did. It could possibly make YOU the Mocomi Kid of the month and get you featured on our website.
