Air and road temperatures substantially affect road vehicle noise emission. The temperature influence on tyre/road noise depends mainly on tyre-road combination. It is different for dense and porous pavements, for bituminous and cement ones. It differs also depending on tyres. The correction procedures for temperature effect are still under consideration and preparation. Tyre/road noise measurements using CPX method were performed to establish correlation between noise emission and ambient temperature for a set of ten selected tyres (characterized by a wide range of noise levels and including the two ISO reference tyres) on a SMA8 dense pavement within the recommended air temperature range from 5ºC to 30ºC with a step of about 5ºC. Both air and road temperatures were taken into consideration. The results of this experiment were presented and discussed in the paper. A good correlation between air and road surface temperature was outlined. A linear relationship between noise emission and temperature was observed for eight tested tyres. The derived temperature correction factor was varied from -0.067 dB/ºC to -0.145 dB/ºC with an average of -0.107 dB/ºC (-0.09 dB/ºC for the two ISO reference tyres). There was no correlation for the remaining two tested tyres.
