The main source of noise is, of course, aircraft during take-off, landing and taxiing. Aircraft noise varies according to type of aircraft, the number of flights, the areas being flown over, time of day, etc. The weather and wind conditions also affect sound propagation. Other sources of noise, such as ground vehicles, generators, testing aircraft engines and long queues of aircraft waiting to take off, can also be bothersome. In winter, snow clearing often disturbs our neighbours.
OSL has a charting system and continuously monitors conditions around the airport. An advanced noise and track monitoring system provides data for the regular monthly reports to the Civil Aviation Authority - Norway.
The aircraft noise zone maps keep the local authorities informed about expected developments in future aircraft noise levels. Large amounts of resources are invested in monitoring the noise situation around the airport, using the noise and track monitoring system (NTMS). Noise zone maps are also drawn up for the areas around the airport.
