Aircraft Noise

An increasing number of airports face operational restrictions due to environmental impact limitations.

More than 130 airports worldwide have some type of noise surcharges, which means that noise is an important parameter for their day-to-day operations. Inaccurate noise predictions require high tolerance margins in order not to exceed existing limits and thus face possible penalties. This may impose unnecessary limitations on land use and on operational procedures. Future environmental noise regulations may become increasingly stricter. It is therefore of vital importance to be able to calculate and predict noise impact to the environment with a very high degree of accuracy and consequently be able to operate the airport at maximum capacity.

SINTEF has a long standing reputation for developing aircraft noise prediction tools. We were the first one to introduce topography corrections in the models, and our fast and effective algorithms allow real time calculations on a per-flight basis. Thus noise can eventually be included in the ATM decision support process for a higher utilization of the airport's environmental capacity.

SINTEF has now started the development of next generation noise prediction tools. Improved input data such as radar tracking and possible access to flight deck parameters will yield more accurate results. This will enable airports to operate even more efficiently within given environmental noise constraints.

SINTEF has a long experience in cooperation with leading aviation authorities such as FAA and Eurocontrol, and in participation in European research projects. SINTEF is part of the NATMIG consortium, and an active partner in a wide range of SESAR activities.
