According to Noise Pollution (Regulation and Control) Rules in India, noise (Leq) in educational institutions during night time (10pm-6am) must not exceed

Correct option is B

The Noise Pollution (Regulation and Control) Rules, 2000, in India classify educational institutions under silent zones. According to the rules, the permissible noise level in silent zones during nighttime (10 pm to 6 am) is 40 decibels (dB). This regulation ensures a peaceful and conducive environment for learning and rest in these sensitive areas.
Information Booster: · Silent Zones: Areas within 100 meters of premises like educational institutions, hospitals, and courts are designated as silent zones.
· Permissible Noise Levels: For silent zones, the daytime (6 am to 10 pm) limit is 50 dB, while the nighttime limit is 40 dB.
These limits are stricter than those for residential or commercial areas, reflecting the need to minimize disturbances in such sensitive environments.
Additional Knowledge: · 35 dB: This is generally considered a very low level of noise and not practical for ambient urban environments.
· 45 dB: While stricter than most standards, it applies to some other classifications and not to educational silent zones.
· 50 dB: This is the daytime limit for silent zones, not nighttime
