Abstract

Researches have been found that noise level fluctuation is important in causing nuisance to human beings but at present, there is no such prediction scheme for noise level distribution. In this study, a single receiver with multiple moving noise sources propagation model is developed. With the inputs of site geometry, traffic volume compositions and its vehicle speed for each road lane, the model can simulate the noise level distribution at the receiver for a period of time and from this distribution, noise statistics such as L A10, LA50 and LA90 due to road traffic noise can be found easily. The outcome of this model has been validated with the 30 minutes road traffic noise surveys and the discrepancies are found to be less than 0.2 dBA.
