26、ion of measurement uncertainties in building acoustics: Part 1: Sound insulation A part 2 dealing with sound absorption is under preparation. DIN EN ISO 12999-1:2014-09 “ ”IntroductionAn assessment of uncertainties that is comprehensible and close to reality is indispensable for many questions in bu
27、ilding acoustics. Whether a requirement is met, a laboratory delivers correct results or the acoustic properties of a product are better than the same properties of some other product can be decided only by adequately assessing the uncertainties associated with the quantities under consideration.Unc
28、ertainties should preferably be determined following the principles of ISO/IEC Guide 98-3. This Guide specifies a detailed procedure for the uncertainty evaluation that is based upon a complete mathematical model of the measurement procedure. At the current knowledge, it seems to be impossible to fo
29、rmulate these models for the different quantities in building acoustics. Therefore, only the principles of such an uncertainty assessment are explained.To come to uncertainties all the same, the concept of reproducibility and repeatability is incorporated which is the traditional way of uncertainty
30、determination in building acoustics. This concept offers the possibility to state the uncertainty of a method and of measurements carried out according to the method, based on the results of inter-laboratory measurements.EN ISO 12999-1:2014(E)DIN EN ISO 12999-1:2014-09 41 ScopeThis part of ISO 12999

47、important ones and how these contributions can be reduced. Furthermore, such a budget reflects the individual sound fields during the measurement. Consequently, the uncertainty is valid for an individual measurement result and not for a whole family of results. Annex C gives provisions on the deriva
48、tion of such uncertainty budgets.5 Uncertainty determination by inter-laboratory measurements5.1 GeneralStandard deviations determined by inter-laboratory measurements may serve as an estimate for the standard uncertainty. The general concept and the procedure for determining these standard deviations are given in ISO 5725-1 and ISO 5725-2, respectively. As many operators and laboratories as possible should participate in such inter-laboratory measurements in order to obtain reliable results
