Question

Which of the following measures does not help in controlling noise pollution in residential areas?

• A. Setting up industries away from residential areas
• B. Restriction on unnecessary honking
• C. Cutting down trees to develop broader roads so that they do not honk while passing
• D. Restriction on playing loud music

Answer 1

The correct option is C Cutting down trees to develop broader roads so that they do not honk while passing

Noise is an unwanted, undesirable sound. Noise pollution can be defined as a disturbing and unwanted sound that harms humans or wildlife.

Exposing humans or animals to high intensity sound or prolonged exposure to noise can affect their health.

To control noise pollution in residential areas following measures can be taken :

• Industries should be set up away from residential areas.
  
• Old vehicles and machines should be maintained properly which usually produce a lot of noise.
  
• Restrictions on unnecessary honking or playing loud music.
  
• Planting more and more trees along the roadside helps in controlling the noise pollution as they serve as good sound absorbers.

Hence options a, b and d are incorrect.

Cutting down trees will create more space for the road but honking can not be stopped. Moreover, it will further increase the noise level as there will be no absorbers for noise or sound. It will result in low oxygen levels, climate changes, changes in rainfall pattern, etc. Hence option c is correct.
