“…criteria in terms of weighted sound reduction index (R w ) and minimum sound reduction (D w ) between rooms 12 . However, in the light of many studies conducted in Europe 20,21 and wide usage of spectrum adaptation terms (C, C tr ) the National Building Codes have to be amended utilizing the weighted standardized field-level difference, D nT,w as the descriptor used for in situ measurement of sound insulation. Table 2 shows the proposed criteria 14 and descriptors for building elements based on the exhaustive literature survey.…”

“…The calculations have been performed according to the following steps:  Using the data of the complete set of airborne sound insulation measurements (1.099), the seven most adopted single number descriptors for airborne sound insulation around Europe [7] were calculated (that is R'w ; R'w + C ; R'w + C(50-3150Hz); DnT,w ; DnT,w + Ctr ; DnT,w + C ; DnT,A (100-5KHz))  DnT,50 and DnT,100 were also calculated.  Pearson correlation coefficient between DnT,50 / DnT,100 and the seven airborne sound insulation descriptors was calculated.…”

Translation between existing and proposed harmonized airborne sound insulation descriptors: A statistical approach based on in-situ measurements

et al. 2017

A standard defining a common acoustic classification scheme for dwellings is under development by ISO TC42/SC2/WG29 based on the outcomes of European project COST Action TU0901. The proposal stands on the assumption that in the long term many countries will establish building acoustic requirements using a harmonized set of descriptors. In this scenario most countries will need to estimate the influence on their current airborne sound insulation requirements due to the new descriptor. This paper investigates a statistical method to obtain translation equations between existing and proposed descriptors, based on the analysis of a significant set of in-situ measurements. Several translation equations are proposed, and the effect of the building system such as heavy and light weight walls. Results show that, although it is possible to propose a single translation equation for each existent descriptor, in some cases the spread around the proposed translation line is significant. Overall, the effect of building system is more noticeable if different frequency range descriptors are involved in the translation. For some existent descriptors, the obtained translation is compared with the theoretical method proposed within the findings of COST TU0901. When considering only lightweight walls or the full data set, there is no good agr eement between both methods, but for heavyweight walls they converge. Existing requirements in most European countries have been translated into the proposed descriptor DnT,50 ≈ DnT,w + C50-3150 using the obtained equations. This provides valuable information and an insight for government and building regulation policy makers when updating their legislation.

“…Warnock (1990) reports in this regard provides a large data bank on sound transmission through concrete blocks attached with gypsum boards. The recent studies conducted by Rasmussen (2010), Rasmussen, Rindel (2010) and Scholl et al (2011) pertaining to the sound regulation criteria in terms of Weighted Standardized Field Level Difference D nT,w and recommendation of fulfilling the criteria D nT,w + C 50−3150 ≥ 55 dB thus essentially implicates the need of experimental investigations for measuring the sound transmission loss of masonry structures in conjunction with dry wall technology. These investigations are essentially required to ascertain their suitability of meeting the acoustic comfort criteria with an objective of strengthening the building facades.…”

“…However, there is no threshold value prescribed for acoustic comfort criteria in dwellings. Recent studies recommend the use of Weighted Standardized Field Level Difference, D nT,w in sound regulation requirements in dwellings (Scholl et al, 2011;Rasmussen, 2010;Rasmussen, Rindel, 2010). R w + C tr is a single-number rating suitable for building facades for evaluating their sound insulation towards traffic noise.…”

The paper presents application of Taguchi method in optimizing the sound transmission loss through sandwich gypsum constructions and those comprising of masonry concrete blocks and gypsum boards in order to investigate the relative influence of the various parameters affecting the sound transmission loss. The application of Taguchi method for optimizing sound transmission loss has been rarely reported. The present work uses the results analytically predicted on "Insul" software for various sandwich material configurations as desired by each experimental run in an L8 orthogonal array. The relative importance of the parameters on single-number rating, Rw (C, Ctr) is evaluated in terms of percentage contribution using Analysis of Variance (ANOVA). The ANOVA method reveals that type of studs, steel stud frame and number of gypsum layers attached are the key factors controlling the sound transmission loss characteristics of sandwich multi-layered constructions.
