CPCB Daytime Noise Limit for Busy Airports

The Central Pollution Control Board (CPCB) is the primary environmental regulatory body in India. It is responsible for setting and enforcing standards related to environmental protection, including the control of noise pollution.

Understanding Airport Noise Regulations

Busy airports are recognized as areas with high levels of activity and potential noise generation from aircraft, ground operations, and associated infrastructure. To protect the health and well-being of people in and around these areas, CPCB establishes specific noise level guidelines. These guidelines differentiate between daytime (usually defined as 6:00 AM to 9:00 PM) and nighttime (9:00 PM to 6:00 AM) periods, as noise can be more disruptive during quieter nighttime hours.

CPCB Noise Standards Overview

CPCB classifies different zones based on their primary land use and activity levels, assigning distinct noise limits to each. Common categories include Industrial Areas, Commercial Areas, Residential Areas, and Silence Zones (areas like hospitals and educational institutions). While airports may not be explicitly listed as a separate category in all CPCB documents, their noise management often aligns with standards set for zones with significant industrial or commercial activity, due to the nature of operations.

The general ambient noise standards prescribed by the CPCB are:

For a busy airport environment, managing noise during the daytime is crucial. Considering the operational intensity and the need to balance activity with environmental regulations, the CPCB guidelines specify an acceptable daytime noise limit. Based on these standards and regulatory practices for highly active zones, the acceptable noise limit during the day in such environments is established at 70 \text{ dB}.
