Abstract : Noise Exposure Forecast (NEF) contours resulting from 1967, 1970, and 1975 aircraft operations are depicted for 28 airports. Included are contours for large, medium and small commercial airports and general aviation airports. The NEF contours define land areas having different land-use compatibility with respect to aircraft noise; hence, the NEF AREAS MAY BE USED AS A GUIDE TO LAND-USE PLANNING AND ZONING AND AIRPORT DEVELOPMENT. The NEF contours are based upon the aircraft noise described in terms of effective perceived noise levels (which includes corrections for duration and presence of discrete frequencies) plus adjustments for the number of operations for daytime and nighttime periods.
