What is the standard noise level proposed by the Central Board for Pollution Control for residential areas during the night?

Correct option is C

The correct answer is (C) 45db.

Explanation:

• The Central Pollution Control Board (CPCB) has recommended a standard noise level of 45 decibels (dB) for residential areas during the night. This is to maintain a moderate noise environment and minimize disturbances in areas where people sleep.

Information Booster:

• Central Pollution Control Board (CPCB): The governing authority responsible for regulating environmental standards in India.
• Ministry of Environment, Forest and Climate Change: Oversees the CPCB, with Bhupender Yadav serving as the Minister (2025).
• Noise Pollution (Regulation and Control) Rules, 2000: These rules set specific noise limits for different areas (residential, commercial, industrial, etc.), with particular emphasis on reducing noise pollution in residential areas during night hours.

Additional Information:

• 25db: Incorrect. This is too low and not a typical standard for residential noise levels.
• 35db: Incorrect. Although quieter, this level is more suitable for very quiet areas, not typical residential environments.
• 65db: Incorrect. This is higher than the standard permissible noise level for residential areas at night.
