Aircraft Noise Exposure: The Cycle Of Modelling,Monitoring And Validation

Especially in highly dense populated areas, like The Netherlands, environmental aspects are, and always have been, a major issue in the relationship between airports and their neighbours. To deal with these aspects, airport and governmental authorities must have adequate information. In the early eighties this information often was limited to the noise level registration for a small number of (fixed) monitoring positions only. To gain additional knowledge about the environmental aspects related to the still ongoing growth of air transport, airports realised more and more complex noise and flight track monitoring systems. These complex systems provide an increasing amount of (correlated) data and functionality, related to noise and track monitoring, noise exposure calculation and complaint analysis. Information, obtained from life data, is used to validate and further optimise modelling used for e.g. airport planning purposes. As a next step, monitoring systems nowadays becomes increasingly important in what can be regarded as a closed-loop process of information gathering, processes of planning and regulation based on this information. Airports and authorities in this way are provided with tools and information to manage impacts on the environment, as related to aircraft noise
