Summary:

The paper presented a correlation work between the GM and Goodyear acoustical laboratories to determine the tire noise load cases used for vehicle tire noise allocation and high-frequency airborne noise analysis. A large group of tires with different sizes were tested in the two labs to examine the lab-to-lab load cases differences in terms of near-field sound intensity and far-field sound power. A good agreement was found for the noise ranking between the two labs by 1/3 octave band and overall A-weighted sound intensity and sound power. The correction factors could be determined from one lab to another as well as from the near-field sound intensity to the far-field sound power. The discrepancies were investigated by comparing the two fixtures and two dyno shell profiles. The differences in 1/3 octave band sound measurement between the two labs were found to be contributed mainly by the shell profiles
