Abstract: In Europe, in situ measurements of sound reflection and airborne sound insulation of noise barriers are usually
done according to CEN/TS 1793-5. This method has been improved substantially during the EU funded QUIESST collaborative project. Within the same framework, an inter-laboratory test has been carried out to assess the repeatability and reproducibility of the newly developed method when applied to real-life samples, including the effect of outdoor weather variability and sample ageing. This article presents the statistical analysis of the inter-laboratory test results, and the values of the repeatability and the reproducibility, both in one-third
octave bands and for the single-number ratings. The stimated reproducibility values can be used as the extended
measure of uncertainty at the 95% credibility level in compliance with the ISO GUM. The repeatability and reproducibility values associated with airborne sound insulation are also compared with the corresponding values
for laboratory measurements in building acoustics and an acceptable agreement is found.
