TIRE NOISE GENERATION: THE ROLES OF TIRE AND ROAD

A hemi-anechoic room and roadwheel facility, for the study of noise from small automobile tires, has been constructed at Stanford University. Through use of the signal average, (roadwheel) tire noise may be separated into tire-rotation correlated and roadwheel-rotation correlated components which account for essentially all of the sound. Level and spectral characteristics of these components are examined for three tires with very simple tread patterns and one commercial type tire. The "groove pipe resonance" is discussed. Problems in coastby-roadwheel noise measurement correlation are examined. /GMRL/
