ICAO DOC 9911 Recomended Method for Computing Noise Contours Around Airports Ed 2
This manual, which replaces Circular 205, is intended to assist States in the computation of noise contours around airports, using the most up-to-date procedures and the most recent aircraft noise and performance information available. It includes three different ways in which most practical noise models calculate aeroplane single event noise levels and is designed to make use of an online international aircraft noise and performance (ANP) database.
