Traffic noise survey and analysis in Singapore

Abstract

A comprehensive survey and statistical analysis of daytime traffic noise in Singapore was carried out. The results are presented in terms of average L10, L50 and L90 for four different classes of sites. By clearly distinguishing between temporal and spatial noise fluctuations, it is possible, on the basis of the Gaussian noise distributions obtained, to verify that the overall noise fluctuation can also be derivable from the respective temporal and spatial noise fluctuations. The traffic noise index (TNI) and the noise pollution index (LNP) are determined and a correlation is established between the traffic noise levels and the corresponding volume of traffic. © 1985.
