Question

Which of the following is NOT helpful in reducing noise pollution?

• A. Using noise absorbers in noisy machineries.
  
• B. Using proper lubrication and better maintenance in machines.
  
• C. Shutting the door while using noisy machines.
  
• D. Playing loud music at night.
  

Answer 1

The correct option is D Playing loud music at night.


Using noise absorbers and shutting doors while using noisy machines does not allow sound to propagate much. Proper lubrication in machines reduces noise by reducing friction between the surfaces. Loud music can also produce noise pollution.
