What is the Integrated Noise Model?
The Federal Aviation Administration’s (FAA), Office of Environment and Energy (AEE-100) has developed the Integrated Noise Model (INM) for evaluating aircraft noise impacts in the vicinity of airports. The INM has been the FAA’s standard tool since 1978 for determining the predicted noise exposure in the vicinity of airports. The FAA requires the use of INM to develop noise exposure contours in FAR Part 150 Noise and Land Use Compatibility Studies. The INM utilizes flight track information, aircraft fleet mix, standard and user defined aircraft profiles and terrain as inputs. The INM produces noise exposure contours that are used for land use compatibility maps. The INM includes built-in tools for comparing contours and utilities that facilitate easy export to commercial Geographic Information Systems. The INM also calculates noise levels at specific sites such as hospitals, schools or other sensitive locations.
