Acoustique — Spécification des surfaces d'essai pour le mesurage du son émis par les véhicules routiers et leurs pneumatiques

This document specifies the essential characteristics of a test track surface intended to be used for measuring rolling sound emission of vehicles and their tyres.

The surface design given in this document

—    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,

—    limits absorption of the vehicle sound sources, and

—    is consistent with road-building practice.
