Question

Which of the following cause noise pollution?

• A. Aeroplanes
• B. Firecrackers
• C. Loud music
• D. River flow

Answer 1

Answer: (A), (B), (C)

The correct options are
A Aeroplanes
B Firecrackers
C Loud music

Noise is the unwanted sound that is unpleasant to hear. Following are some examples of noise pollution:

• Noise produced by heavy machines and firecrackers
• Noise produced by aeroplanes and factories
• Loud music during parties and festivals

However, the sound produced from the flowing of a river is not loud and unpleasant, rather is calming and subtle. So, it is not considered a cause of noise pollution.
