Acoustics. Measurement of the influence of road surfaces on traffic noise - The close-proximity method Ingestion-build-1430741 Scope This document 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 countries it is possible that tyre road noise does not
