What is airport noise compatibility planning?
What is airport noise compatibility planning? A Noise Compatibility Program (NCP) identifies measures the airport operator has taken or proposes to take to reduce, and/or prevent the introduction of, noncompatible land uses.
WHO guidelines for airplane noise?
For average noise exposure, the GDG strongly recommends reducing noise levels produced by aircraft to below 45 dB Lden, as aircraft noise above this level is associated with adverse health effects.
What causes airport noise?
When air passes over the aircraft's airframe, it causes friction and turbulence, which results in noise. Planes land with their flaps down which creates more friction and produces more noise than a plane with its flaps up.
