This manuscript denotes the results of the Interlaboratory Comparisons (ILC) conducted to test the proficiency of accredited laboratories (23) according to in situ measurement methods described in ISO 16283-1:2014/A1:2017, ISO 16283-2:2020 with ISO 717-1:2020 and ISO 717-2:2020. The comparison of all measured parameters and single number building acoustic parameters is presented with attained measurement uncertainties. The overall influence of all uncertainty components on the final results is taken account for sound reduction index and normalized impact sound pressure levels. The measurement uncertainties are obtained by performing one independent measurement from each laboratory and they are determined at the end for all results in reproducibility and repeatability conditions. The obtained values for measurement uncertainties are compared with values given in standard ISO 12999-1:2020 and with previous ILC2015-s results for airborne and impact sound insulation parameters when five independent measurements have been done. The experimental measurement uncertainties for single number results are lower (in average 0.3 dB for u(R′w) and in average 1 dB for (L′n,w)) than values given in standard ISO 12999-1:2020. The experimental measurement uncertainties calculated from reproducibility in one-third octave bands are not smoothed compared to the situation when five independent measurements are done.
