Acoustics - Specification of test tracks for measuring noise emitted by road vehicles and their tyres (:2014)
N ISO 10844
Annotation
This International Standard 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 this International Standard
— 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.
NOTE For the purposes of this International Standard, the terms noise and sound are used interchangeably.
