Assessment of the environmental impacts of audible noise produced by human activities -- such as construction and operation of industrial facilities, vehicular traffic, and aircraft operations -- requires the use of sound-propagation computer programs capable of predicting the sound-pressure spectra that will be produced by these noise sources at distances as great as 10 km. Under acoustically unfavorable meteorological conditions, such as ground-based temperature inversions and noise-sensitive receptors being located downwind from intrusive sound sources, audible noise levels can be increased, even on the order of 20 dB. This paper presents a brief overview of computer programs currently available (``operational``) for predicting the effects of such meteorological conditions on audible noise levels in a format that allows gross comparison of the relative capabilities of the programs from the standpoint of engineering application to environmental impact assessment.
