Résumé

The paper deals with the relation between numerical contact data and close-proximity (CPX) noise measurements. The noise was measured on several road surfaces together with the texture in three dimensions on two-meter-long sections. A multi-asperity contact model was used to obtain successively the contact forces distribution and the contact pressure distribution between a patterned standard tyre and the road during rolling. The correlation between third-octave contact force levels and noise levels was studied on a set of ten surfaces. A high positive correlation is found at low frequency below 800 Hz, which allows the estimation of noise levels by means of statistical relations for each third-octave band between 315 Hz and 800 Hz. The results of the model are discussed in relation to the standard deviation of CPX measurements.
