During day time, noise pollution in residential area should not exceed ....................... .

  • A.75 dB
  • B.55 dB
  • C.65 dB
  • D.80 dB

Answer: B

The daytime limit for residential areas is 55 dB.

The Noise Pollution (Regulation and Control) Rules, 2000 set daytime limits of 75 dB(A) for industrial areas, 65 dB(A) for commercial areas, 55 dB(A) for residential areas and 50 dB(A) for silence zones. The night limit for residential areas is 45 dB(A).

75 dB and 65 dB are the industrial and commercial limits, and 80 dB is not among the ambient standards.
