A comparison is made of the sound-level predictions by two highway traffic-noise-prediction programs--the Simplified Noise-Analysis Program (SNAP 1.0) and the Standard Method in Noise Analysis (STAMINA 1.0). These programs were published in 1979 by the Federal Highway Administration. The purpose of the study was to determine whether the two programs yield the same Leq and L10 sound-level predictions given the same simple site parameters. To accomplish this, computer runs were formulated to compare the handling of angular adjustments, dropoff rate as distance was changed, barrier attentuations, and nonparallel roadway segments by the two programs. Based on the data compiled for this paper and the resulting changes planned to be made to the programs, the user may feel confident that the SNAP and STAMINA programs will yield the same Leq values if given the same site parameters in almost all cases. The L10 predictions also agree well except in cases in which ratios of number of vehicles and distance to speed occur that are below 30 m/km. (Author)
