“…Because the uncertainty of R IS is smaller than that of R for all these parameters, the reproducibility of R IS will be better for small-sized test elements. This is in line with measurement results on small-sized test elements [1,18].…”

“…The measurements were also used to estimate the average differences between the two methods. In a Nordic round robin test with five laboratories [18], the reproducibility values for a double glazed window were decreased significantly by use of the adapted intensity method. The values were in good agreement with the estimated reproducibility values in the standard.…”

An extensive parametric study has been carried out with a wave based model to numerically investigate the fundamental repeatability and reproducibility of labo- elements, the reproducibility of the intensity method is better. For heavy walls and lightweight double constructions, however, the predicted uncertainty is similar for the three measurement methods. The results of the reproducibility study are also used to investigate systematic differences between the pressure method and both intensity methods.

“…Even though this noise type has been used in at least two listening tests [1,35], a recent residential survey suggests that this kind of living sound seems to be quite rare in dwellings [30,36]. The widening of the measured frequency range down to 50 Hz might also lead to problems in measurement uncertainty [37]. Thus, our study does not support the frequency range to be widened down to 50 Hz regarding airborne sound insulation measurements.…”

“…A comparison will be made with 95% confidence intervals for the airborne sound insulation that have been proposed in the form of reproducibility values. [16][17][18] They are based on a limited number of interlaboratory experiments for three different wall types and provide a rough indication of the accuracy that can be expected.…”

A probabilistic framework is developed for quantifying the combined effect of uncertain parameters in sound insulation measurements, such as test sample dimensions, room properties, and loudspeaker positions, on the sound insulation values. The joint probability distribution of the uncertain parameters is constructed from the available information by means of a maximum entropy approach. The resulting sound insulation predictions are fully compatible with the available information but otherwise maximally conservative, so that the robustness of the predictions is guaranteed. Fundamental insight in the inherent uncertainty of the measurement procedure for airborne sound insulation is obtained by combining the method with detailed numerical simulations of the measurement procedure for single and double walls. The resulting uncertainty levels are very large, especially in the lowest frequency bands, and agree with experimental results. Furthermore, the probability distribution of the band-averaged sound reduction index of modally sparse walls can be of bimodal form.
