INVESTIGATIONS CONCERNING TYRE/ROAD NOISE SOURCES AND POSSIBILITIES OF NOISE REDUCTION
Using different measurement methods, the many possible mechanisms generating tyre rolling noise were investigated. The knowledge of these noise generating processes led to a range of possibilities for reducing tyre noise, each possibility resulting in a small noise reduction. Details are given of the measurement methods used in the study, of the results obtained concerning the influence of the tread profile and road surface, and vibrations in the contact area. The sound pressure was also measured in the tread grooves together with the radiated rolling noise measured at the leading and trailing edge of a special tyre.
