Aircraft noise

Land located close to airports and flight paths may be subject to aircraft noise. This noise is classified in 3 ways:

  • mechanical noise — rotation of the engine parts, most noticeable when fan blades reach supersonic speeds
  • aerodynamic noise — from the airflow around the surfaces of the aircraft, especially when flying low at high speeds
  • noise from aircraft systems — cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units

The Aviation Policy Framework outlines planning considerations with regards to aircraft noise
