Meteorological influences on the transmission of traffic noise. Paper presented at the International Conference on Noise Control Engineering, Warsaw, September 11-13, 1979.

Under various meteorological conditions 170 sets of measurements have been made of sound from a straight motorway. Each set consists of a reference measurement near the road and corresponding measurements at remote positions. Large variations occurred which can be linked to influences of wind and temperature gradients. A set of meteorological conditions (meteo-window) is presented which allows fairly reproducible immission measurements.
