Abstract
The United States Federal Highway Administration (FHWA) computer program STAMINA 2.0 was evaluated with the ground attenuation algorithm used in the Ontario Road Noise Analysis Method for Environment and Transportation (ORNAMENT). The goal: To determine this method’s potential to improve noise level predictions at receivers located near traffic roadways with barriers in the propagation path. The study of 41 sites indicated that this method reduced the mean overprediction of noise levels from 2.6 dB using STAMINA 2.0 alone, to 0.5 dB using STAMINA 2.0 with the ORNAMENT ground attenuation algorithm.
