Abstract : A methodology called Noise Exposure Forecasts (NEF) is developed for describing aircraft noise exposure in the vicinity of the takeoff and approach flight paths of an airport. In support of this methodology an improved measure of the subjective response to aircraft flyover noise called Effective Perceived Noise Level (EPNL) has been derived. This measure includes corrections for pure tone components and duration. Other elements necessary for the calculation of NEF are number of exposures and time of day. NEF contour are translated into guidelines for compatible land use. (Author)
