Abstract
Ground effect and refraction modify geometrical spreading. In the present study a simplified model of ground effect is applied. Refraction is analyzed for the motionless atmosphere with a linear sound speed profile. Noise generated by constant speed road traffic is assessed by the time-average sound level, LAeqT. The model of LAeqTprediction contains free parameters that are estimated from noise measurements at the site in question. The model makes possible the prediction of LAeqT at an altitude of a few tens of meters above the ground surface, within the range of a few hundred meters from the road. Contours of LAeqT=constant in the vertical plane represent the radiation pattern of road traffic noise. © 1997 Elsevier Science Ltd.
