Abstract

The aim of this study is to evaluate the suitability of stationary and mobile techniques for measuring traffic noise on different road surfaces by directly comparing the results obtained with both techniques. The results show that significant differences were observed in the levels of noise emitted from various types of road pavements. The relative differences found with both methods were broadly comparable. It can be concluded that both methods have advantages and disadvantages. The results bring into question the suitability of the stationary method for characterizing the influence of road surface on traffic noise, as the latter method relies on fixed reception points. Therefore, it seems that for characterizing the influence of road surface on traffic noise the trailer method is most suitable, while for characterizing the noise level at the receiver alongside the road the traffic method is preferable.
