Tyre/road noise modelling - noise measurements of 12 passenger car tyres

Abstract

Noise measurements of 12 passenger car tyres have been made on 7 dense asphalt concrete surfaces in Norway. The tyres are typical for replacement tyres (after-market) in Norway and the road surfaces also represent pavements types widely used in Norway. Partly, the measurements have been performed to investigate the noise ranking of these tyres and partly as a basis for a modelling project, using the SPERoN hybrid model for tyre/road noise. The noise measurements have been done, using the CPX-trailer of the Norwegian Public Road Administration, according to the method described in ISO/CD 11819-2, where the noise is measured with microphones close to the tyres.The results show a noise difference of 2-3 dB(A) between the tyres at a speed range of 50-80 km/h.
