An analytical model of a typical community has been developed for the purpose of carrying out a cost-effectiveness analysis of various outdoor noise countermeasures. The principal elements of the model are (1) A data base describing the community's geography, population distribution, and typical building construction; (2) a data base describing the location and strength of noise sources; (3) energy summation of noise levels from each source at many locations; and (4) use of noise level versus human response transfer functions to determine the number of people adversely affected by this noise level. Summing these for the whole community and dividing by the total population results in a 'Noise Impact Index (NII)' indicating the quality of the noise environment. Three basic types of countermeasures may be applied: (1) source reduction, (2) source rerouting, and (3) path-receiver treatments.
