Development of a computer-aided approach to the analysis of aircraft noise as it affects communities near airports is summarized in the report. The major factors that must be described to specify the noise stimulus and the factors which appear to be relevant to description of the community-wide response to that noise are discussed and diagrammed. An approach to analysis of aircraft noise situations that involves close man-computer interaction is formulated and programming to implement this approach is described. Some illustrations of the process are presented. The major computer programs being developed will a calculate perceived noise levels from octave band noise spectra b calculate areas from graphical input data maps, noise contours c calculate and display noise contours for a simulated aircraft flight d calculate the time pattern of noise exposure at a ground position near an aircraft flight path and e calculate and assemble the noise levels occurring at multiple ground positions during a number of simulated aircraft flights.
