In situ measurements of sound reflection and airborne sound insulation of noise barriers are usually done in Europe according to CEN/TS 1793-5. These methods have been substantially improved during the EU funded QUIESST project. In the frame of the same project, an inter-laboratory test has been carried out in order to assess the repeatability and reproducibility of the newly developed methods when applied to real-life samples. In this paper the main outcomes of the QUIESST inter-laboratory test are presented and discussed. The values of repeatability and reproducibility of sound reflection index and airborne sound insulation index are shown both in one-third octave bands and for the single-number ratings.

In this paper the main outcomes of the QUIESST inter-laboratory test are presented and discussed.
