Noise measurements of passenger car tyres at the Kloosterzande test track. Noise ranking, frequency and texture analysis

Abstract

At the Kloosterzande test track in the Netherlands, noise measurements of 22 summer car tyres have been performed on 23 different road surfaces, including an ISO-surface.All measurements have been performed with a CPX-trailer at 50 and 80 km/h. A frequency analysis of all combinations of tyres and road surfaces has been made. A ranking analysis of noise levels is included, where the ranking on the on the ISO-surface is compared to the ranking on the other 22 surfaces. Furthermore, a relationship between different texture parameters and the noise levels has been studied.Between the noisiest tyre on the noisiest road surface, and the quietest tyre on the quietest road surface, a difference of 17 dB was found. The difference in road surface noise performance is the most significant reason for this large number.
