Which term describes a policy that regulates noise impact on surrounding communities of an airport?

The term that describes a policy managing the noise impact that an airport has on surrounding communities is "noise abatement." Noise abatement policies are designed to minimize the effects of aviation noise on nearby residents and neighborhoods, often implemented through specific flight paths, operational procedures, and restrictions on certain aircraft types or operations during specific times of the day. These measures aim to reduce the level of noise pollution experienced by communities adjacent to airports, enhancing quality of life while still allowing for efficient airport operations.

Traffic patterns refer to the established routes that aircraft follow when taking off or landing, but they don't specifically focus on noise impact. Taxi pertains to the movement of aircraft on the ground, particularly between the runway and the terminal, and similarly does not directly address noise concerns. Ramp refers to the area where aircraft are parked, loaded, and unloaded, which is also not directly related to the regulation of noise impact on communities. Thus, noise abatement is distinctly the most relevant term in this context.
