ISO 11819-2:2017 specifies a method of evaluating different road surfaces with respect to their influence on traffic noise, under conditions when tyre/road noise dominates. The interpretation of the results applies to free-flowing traffic travelling on essentially level roads at constant speeds of 40 km/h and upwards, in which cases tyre/road noise is assumed to dominate (although in some…

ISO 11819-2:2017 décrit une méthode d'évaluation de différents revêtements de chaussée en ce qui concerne leur influence sur le bruit émis par la circulation, dans des conditions où prédomine le bruit de contact pneumatique/chaussée. L'interprétation des résultats s'applique à des véhicules se déplaçant dans des conditions de circulation fluide sur des routes sensiblement planes à…
