- Summary:
- AbstractThere is a great lack of Brazilian laboratory and field measurements on of noise generated by the interaction between tyre and road surface. In this study the tyre-road noise interaction on Brazilian roads through the CPX method with a wheeled trailer with enclosure that simulates a light vehicle of 700 kg equipped with two tyres and two microphones for each tyre is evaluated. Two types of sections of the road with different surfaces characteristics were evaluated with the trailer at speed of 80 km/h. The first section road is comprised of a rubberized asphalt mixture about 30 months of age and the other surface is composed of an ordinary dense asphalt mixes with approximately 10 years of age. The noise generated by the tyre-road showed that the sound pressure levels are concentrated between 630 and 1600 Hz and the differences in the sound levels are related with the characteristics and ages of the road surface
