A road test on acoustic wheel roughness measurement

Within the preparation of the next revision of the European acoustic roughness measurement standard EN15610 some group members carried out a joint measurement exercise. This gave evidence, that all participants had the same idea of the measurement task and the procedure to collect an appropriate set of measurement data.Six different sets of data, defined by the combination of a measurement kit and an operator were collected. Each set consists of a selection of traces in the center area of the running band. All data have been analyzed with the software associated with the measurement device and additionally all with the same software. The exercise demonstrated, that all measurement kits produce sufficient data.The presentation gives detailed results on influences from surface preparation, operators, measurement devices and software.
