"This study demonstrates the feasibility of automating a procedure for counting the number of people exposed to various levels of aircraft noise near airbases. The procedure involves: developing contours of equal noise exposure about military installations based on aircraft noise and performance data and airport operational/flight track information using the NOISEMAP computer program; developing polygon descriptions of the noise contours that are compatible with commercially available demographic programs using census tract data; and outputing for land use planning purposes, demographic and socio-economic data for present or future years as a function of predicted noise exposure level."@en . . . . . . . . . .
