Noise exposure maps (PEB) which define land use zoning around airports and noise insulation maps (PGS) are based on noise contours. Calculation of these noise contours depends on several parameters: the number and the type of movements, day-evening-night trafic distribution, temperature, topography, tracks lateral dispersion, glide slope, climb slope...
The aim of this study is to evaluate the impact of each parameter on noise contours.
The final objectives of this analysis asked by ACNUSA are:
- to identify the most sensitive parameters to focus on these;
- to better undestand noise model behaviour.
