The results of direct sound insulation tests of wall and floor assemblies were reported at EURONOISE 2015 and INTERNOISE 2015. This paper focuses on flanking sound transmission in cold-formed steel-framed constructions. A representative full-scale mock-up specimen was constructed in NRC's 8-room flanking transmission facility. The specimen consists of four loadbearing walls with 152 mm deep steel studs, four non-loadbearing walls with 92mm deep steel studs, and four floor-ceiling assemblies consisting of steel joists and a composite steel deck with gypsum concrete. Measurements were conducted according to the indirect method described in ISO 10848. The individual flanking paths were measured by a sequence of transmission loss measurements in which other transmission paths were suppressed by shielding. For the bare specimen without linings, the sound transmission for horizontally adjacent rooms with continuous subfloors is dominated by the floor-floor flanking paths. Floor coverings or floor toppings are needed to meet the requirements in the National Building Code of Canada. This paper presents details of the measurements, highlights some of the results and discusses implications.}, language = {en} } @inproceedings{HoellerZeitlerMahn, author = {H{\"o}ller, Christoph and Zeitler, Berndt and Mahn, Jeffrey}, title = {Direct sound transmission loss of heavy gauge steel stud walls}, series = {Proceedings of Euronoise 2015 : 10th European Congress and Exposition on Noise Control Engineering : Maastricht, 31 May - 3 June 2015}, booktitle = {Proceedings of Euronoise 2015 : 10th European Congress and Exposition on Noise Control Engineering : Maastricht, 31 May - 3 June 2015}, address = {Maastricht}, pages = {1121 -- 1126}, language = {en} } @inproceedings{ZeitlerHoellerMahn, author = {Zeitler, Berndt and H{\"o}ller, Christoph and Mahn, Jeffrey}, title = {Empirical model of direct sound transmission through lightweight wood-framed construction}, series = {Implementing noise control technology : 44th International Congress and Exposition on Noise Control Engineering (Internoise 2015) : San Francisco, California, USA, 9 - 12 August 2015}, booktitle = {Implementing noise control technology : 44th International Congress and Exposition on Noise Control Engineering (Internoise 2015) : San Francisco, California, USA, 9 - 12 August 2015}, publisher = {Curran}, address = {Red Hook, NY}, abstract = {Tools to predict sound transmission through building elements are beneficial from both amarketing and a research standpoint. Prediction models can assist with the optimization ofelement performance and often reduce both cost and time in projects. However, the morephysical phenomena are to be included in the model, the more input data that is needed,which in some cases can be quite time-consuming and costly to collect. A balance is neededbetween the input and modeling effort and the output, which is usually delivered in onethird octave frequency bands or single number ratings. Many different types of models arecommonly used, including analytical, numerical, and empirical are used, all of which haveadvantages and disadvantages. In this paper, the latter type is presented using a set ofphysical properties of lightweight wood elements, and the errors made in the prediction arequantified. The disadvantage of empirical compared to analytical modeling is that thephysical phenomena are more difficult to identify. The advantage is often the simplicityand accuracy of the prediction results.}, language = {en} } @inproceedings{ZeitlerMahnSabourinetal., author = {Zeitler, Berndt and Mahn, Jeffrey and Sabourin, Ivan and H{\"o}ller, Christoph and Schoenwald, Stefan}, title = {Apparent airborne sound insulation of hybrid wood-concrete masonry assemblies}, series = {Euronoise 2015 : 10th European Congress and Exposition on Noise Control Engineering : Maastricht, 31 May - 3 June 2015}, booktitle = {Euronoise 2015 : 10th European Congress and Exposition on Noise Control Engineering : Maastricht, 31 May - 3 June 2015}, address = {Maastricht}, organization = {Belgian Acoustical Association (ABAV), Acoustical Society of the Netherlands (NAG), European Acoustics Association (EAA)}, pages = {2515 -- 2520}, abstract = {As part of a research project to develop design solutions for concrete-masonry buildings for the Canadian market, the apparent sound insulation performance of hybrid assemblies with concrete masonry walls and wood joist floors was evaluated.

The procedure uses the blocked force of the source as input data. This quantity can be determined using the reception plate method according to EN 15657:2017. The methods have been developed and validated for stationary excitation signals (Leq). Real structure-borne sound sources often have time-varying excitation signals. In addition, the requirements for sound insulation against noise from building service equipment in Germany (DIN 4109) are given in terms of the maximum, time-weighted sound pressure level (LFmax). This contribution investigates the suitability of the methods described in EN 12354-5 and EN 15657 for structure-borne sound sources with transient excitation signals. A measurement series with time signals ranging from stationary to highly transient was conducted in a building-like laboratory. The reverberation time of the receiving room was adjusted to three different values. The calculations were processed using Leq values, LFmax values and short-time Leq values. The results show the uncertainties that can arise in the prediction of signals with varying transient characteristics compared to stationary excitation signals.}, language = {en} }
