An in-depth look at the tire rubber hardness influence on tire/road noise measurements
PublicationWhen assessing the acoustic quality of a road pavement with the close-proximity (CPX) or the on-board sound intensity (OBSI) method, the rubber hardness of the reference tire substantially affects the measurement.
