In line with increased awareness of the importance of tire/road noise, the demands for a standardized method for tire/road noise measurement have become urgent. In response to that, the Group of rapporteurs on brakes and running gear (GRRF) within the ECE has established an adhoc group to deal with this topic. Three methods have been seriously considered in this work; coast-by, laboratory drum and trailer. It is hoped that all three methods will be possible to use, although in different situations. Many features of the trailer method are very attractive; however, one serious problem is the disturbances by background noise and especially to quantify this background noise. The report presents the basic methods for trailer background noise estimation together with an analysis of such measurements performed on two trailers.
