Within ISO working group TC43/SC 1/WG33 a new standard is being
prepared (ISO 11819-2: The Close-Proximity Method; CPX) which
describes an acoustic measurement method for road authorities, road
builders and research institutes. With this method, the acoustic properties of
road surfaces can be determined. In this method, special vehicles and near-field microphones are used.
