ISO 10844:2014

ISO 10844:2014 specifies the essential characteristics of a test surface intended to be used for measuring vehicle and tyre or road noise emissions. The surface design given in ISO 10844:2014 produces consistent levels of tyre or road sound emission under a wide range of operating conditions including those appropriate to vehicle sound testing, minimizes inter-site variation, provides minor absorption of the vehicle sound sources, and is consistent with road-building practice.
