The SilVia round-robin test on measurement devices for road surface acoustics

摘要

One of the main objectives of the EU 5th framework project SilVia is to generate a classification system for road surfaces with respect to their influence on the production of road traffic noise. It is aknowledged in SilVia that standardised, representative measurement methods are essential for the assessment of the acoustic properties of road surfaces. These methods can be used for classification of road surfaces, for checking the conformity of production and for monitoring. In July 2003 a round-robin test measurement program was carried out with participants from France (LCPC), Germany (BASt), the Netherlands (DWW and M+P), Poland (TU Gdansk), and the UK (TRL). The objective of this measurement program was to compare measurement devices for CPX, surface texture and sound absorption and to assess their reproducibility and repeatability. The goal, design and some preliminary results of this measurement program are presented in this paper. Final results will comprise recommendations for the application of the different measurement methods for classification purposes.
