    <title language="eng">Airborne and impact sound insulation data for cold-formed steel-framed walls and floors</title>
    <abstract language="eng">This report presents the results of an extensive series of direct sound insulation tests of cold-formed steel-framed walls and floors. The direct airborne sound insulation of 30 walls with cold-formed steel framing was measured in accordance with ASTM E90-09. The walls had steel studs with a depth of 92 mm (3-5/8”) or 152 mm (6”), and with a steel thickness of 1.09 mm (0.043”) or 1.37 mm (0.054”). Other parameters that were investigated included the number of layers and thickness of gypsum board, the cavity insulation, the stud spacing, and the use of resilient channels. The test results for some non-standard wall configurations that were tested for research purposes (e.g. for walls with gypsum board on one side only) are also included in this report. The direct airborne and impact sound insulation of 17 floors with cold-formed steel framing was measured in accordance with ASTM E90-09 and ASTM E492-09, respectively. The floors had steel joists with a depth of 254 mm (10”) or 317 mm (12.5”), and with a steel thickness of 1.37 mm (0.054”). The top surface of the floor/ceiling assemblies was composed of a corrugated steel deck with poured gypsum concrete, while the bottom surface was composed of a gypsum board ceiling on resilient channels. The influence of the joist depth and the number of layers and thickness of the ceiling gypsum board was investigated, as well as the influence of several floor coverings (e.g. laminate or carpet). The report presents the detailed specimen descriptions and specimen properties and the results from the standardized tests according to ASTM E90-09 and ASTM E492-09. Brief analyses of the parameters affecting the sound insulation of the steel-framed assemblies are provided. The tests presented in this report were part of a large research study that also included an investigation into the flanking sound transmission in cold-formed steel-framed buildings. The results of that study are described in the NRC Research Report RR-337, “Apparent Sound Insulation in Cold-Formed Steel-Framed Buildings” [1]. The NRC Research Report RR-337 also includes some of the airborne sound insulation results presented here, albeit without listing the detailed specimen descriptions and specimen properties that are provided in this report.</abstract>

    <title language="eng">Source substitution method for obtaining the power transmission from vibrating sources in buildings</title>
    <abstract language="eng">This paper describes a method analogous to the airborne sound source substitution method, to estimate the vibrational power injected by a structure-borne sound source into the supporting building element. The injected vibrational power is required for prediction of the structure-borne sound pressure from vibrating equipment in buildings. The paper focuses on high-mobility sources connected to low-mobility receivers, a situation which is commonly encountered in heavyweight construction. The mobility mismatch simplifies the transformation of laboratory measurement data to prediction of transmitted power in-situ. Three case studies were performed. In the first study, the power injected by a simple test source into a resiliently supported aluminium plate was determined using direct and indirect methods. Source substitution was investigated with different calibration options: steady-state excitation, transient excitation, and spatial averaging. The source power could be determined within 4 dB, compared with direct measurements of the injected power. In the second study, the power injected by a second source into a concrete transmission suite floor was determined. The third study was of a combined heating and power unit on a masonry wall. In this study, a reference sound pressure level in a receiver room was calculated and compared with a criterion curve for the assessment of low-frequency noise complaints. The case studies demonstrate that structure-borne sound source substitution is a promising development of the reception plate method. While the latter can be used if a free reception plate is available, the former circumvents problems of determining the transmitted power into coupled plates and therefore has application to real building conditions. The use of the instrumented hammer for the calibration and the use of spatial averaging significantly simplify the method.</abstract>

    <title language="eng">Predicting the Interaction Between Structure-Borne Sound Sources and Receiver Structures from Independently Measured Quantities</title>
    <abstract language="eng">Structure-borne sound sources are usually characterised by their source activity and source mobility. By combining this data with the mobility of receiver structures it is theoretically possible to predict the sound pressure level in a building. In a case study of a washing machine on a wooden joist floor this prediction process was investigated. The prediction was based on the normal force component only. The contact area at the feet of the washing machine was made as small as possible to avoid the influence of moments while the in-plane components were assumed negligible. These conditions proved to allow for accurate predictions in the coupled state in a previous publication [1]. The results show that the prediction from independently measured normal source and receiver quantities yields large errors below 125 Hz as a consequence of the above assumption. Between 125 and 900 Hz the error of the prediction is within ± 5 dB. The case study further investigated two assumptions frequently encountered in practice: low and high-mobility sources and no cross-coupling between the feet</abstract>

    <title language="eng">Apparent sound insulation in cross-laminated timber buildings</title>
    <abstract language="eng">This Report presents the results from experimental studies of airborne sound transmission, together with an explanation of calculation procedures to predict the apparent airborne sound transmission between adjacent spaces in a building whose construction is based on cross-laminated timber (CLT) panels. There are several types of CLT constructions which are commercially available in Canada, but this study only focused on CLT panels that have adhesive between the faces of the timber elements in adjacent layers, but no adhesive bonding the adjacent timber elements within a given layer. There were noticeable gaps (up to 3 mm wide) between some of the timber elements comprising each layer of the CLT assembly. These CLT panels could be called “Face-Laminated CLT Panels” but are simply referred to as CLT panels in this Report. Another form of CLT panels has adhesive between the faces of the timber elements in adjacent layers as well as adhesive to bond the adjacent timber elements within a given layer. These are referred to as “Fully-Bonded CLT Panels” in this Report. Because fully-bonded CLT panels have different properties than face-laminated CLT panels, the sound transmission data and predictions in this Report do not apply to fully-bonded CLT panels.</abstract>

    <title language="deu">Indirect determination of the mobility of structure-borne sound sources</title>
    <abstract language="eng">Methods are considered for the indirect determination of the mobility of structure-borne sound sources. Instead of performing measurements on the source in the free state, the source mobility is obtained from measurements made in-situ. This approach is beneficial if the source is difficult to suspend, or if it contains nonlinear structural elements. Two formulations for an indirect source mobility are derived theoretically. The first requires measurement of velocities at or near to the contact points. The second involves measurement of remote velocities only. Neither of the methods requires excitation at the contacts in the coupled state. Numerical simulations of coupled beams are used to validate the two methods and investigate their accuracy and reliability with respect to typical measurement errors, such as background noise and inaccuracies in sensor positioning. It is found that these can have a significant effect on the methods considered. Several experimental case studies with single-contact and multi-contact sources are performed. The results confirm the validity of the two methods in principle, but highlight their sensitivity to experimental errors. In a representative case study with a fan unit, average errors range between ±5 dB and ±10 dB, with occasional errors of up to 30 dB.</abstract>

    <title language="eng">Inverse Method to Obtain Blocked Forces of Vibrating Sound Sources in Buildings</title>
    <abstract language="eng">Vibrating sources, such as building service equipment, are major contributors to noise in buildings. In order to predict and subsequently reduce the sound pressure levels generated by these devices, it is necessary to first predict the total vibrational power injected by them into the supporting building structure. Whilst simplified methods are available for the calculation of the total power through all contacts, it would be beneficial to have more detailed knowledge of the dominant contact powers. For sources on low-mobility building elements, the contact powers are determined by the blocked force, along with the real part of the receiver mobility at each contact. This paper describes a novel inverse method to obtain the blocked forces at each contact. The method employs an instrumented reception plate, which is numerically modelled to allow optimum accelerometer positions to be selected, for any source and any location. The underlying theory and measurement procedure are described, and experimental validations are presented.</abstract>

    <title language="eng">Addendum to RR-335: sound transmission through Nail-Laminated Timber (NLT) assemblies</title>
    <abstract language="eng">This report is published as an addendum to NRC Research Report RR-335 “Apparent Sound Insulation in Cross-Laminated Timber Buildings." It is intended that this addendum will be merged with RR-335 in the future as a report for predicting the sound insulation in buildings using mass-timber constructions including NLT assemblies. This report presents the results from experimental studies of airborne sound transmission through assemblies of nail-laminated timber (NLT) with various linings. To put the data presented in this report in the proper context, this report begins with a brief explanation of calculation procedures to predict the apparent sound transmission class (ASTC) between adjacent spaces in a building whose structure is a combination of mass-timber assemblies such as nail-laminated timber (NLT) or cross-laminated timber (CLT) panels.</abstract>

    <title language="eng">Evaluation of the communication performance of the C4 chemical, biological, radiological and nuclear mask</title>
    <abstract language="eng">The Canadian Armed Forces (CAF) are using chemical, biological, radiological and nuclear (CBRN) general service respirators (GSRs) to defend against CBRN threats and hazards to protect personnel and ensure that they can safely and successfully carry out missions. The CBRN GSR currently in use by the CAF is the C4 respirator. The National Research Council of Canada assessed the communication performance of the C4 respirator. This report presents the results of the performance test. The method for assessing the communication performance used in this study was the NIOSH standard test procedure TEB-CBRN-APR-STP-0313 [1]. Other methods exist to evaluate the communication performance of respirators, but historically the NIOSH standard test procedure has been used. This report details the implementation and results of the tests conducted at the National Research Council of Canada, following the NIOSH standard test procedure.</abstract>

    <title language="eng">Indirect methods of obtaining activity and mobility of structure-borne sound sources</title>
    <abstract language="eng">The work reported in this thesis focuses on the development of indirect methods for the experimental determination of important source parameters for structure-borne sound source characterization. In the first part of the thesis, matrix inversion methods for the determination of blocked forces are investigated. A simplified measurement procedure is proposed which offers a solution to the two major challenges to these methods, namely the acquisition of the FRF matrix and the problems associated with matrix inversion. The proposed procedure involves a free, low-mobility receiver plate which is modelled numerically. Calculated FRFs are used together with measured velocity responses to inversely determine the blocked forces. It is found that while the method has great potential in principle, in practice the accurate modelling of the receiver plate is of critical importance. In the second part of the thesis, three formulations are considered for the indirect determination of source mobility. Instead of performing measurements on the source in the free state, the source mobility is obtained from measurements made in-situ. This approach is beneficial if the source is difficult to suspend, or if it contains non-linear structural elements. The three formulations are validated numerically and experimentally. It is found that the methods can quantify source mobilities of single-contact and multi-contact sources from in-situ measurements. However, typical measurement errors, such as background noise or inaccuracies in sensor positioning, can significantly reduce the accuracy and reliability of the methods. In the final part of the thesis, the reception plate method for the determination of the power injected by a high-mobility source into a low-mobility receiver is reviewed, and a source substitution method proposed as a development. The substitution method circumvents problems that may arise when the reception plate method is applied to coupled walls and floors. A special focus of investigation is on the calibration of the receiver structure. It is found that the calibration can be performed with shaker or hammer, and that an average calibration factor may be used. The source substitution method thus offers a potential alternative to the reception plate method, for application with coupled plates.</abstract>

    <title language="eng">Laboratory study on flanking sound transmission in cold-formed steel-framed constructions</title>
    <abstract language="eng">In a recent study at the National Research Council Canada, the sound transmission in cold-formed steel-framed constructions was investigated. 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.</abstract>

    <title language="eng">Empirical model of direct sound transmission through lightweight wood-framed construction</title>
    <abstract language="eng">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.</abstract>

    <abstract language="eng">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. In this paper, the effect of junction coupling is investigated in an ISO 15712 flanking prediction context. Airborne flanking path data predicted according to ISO 15712 are compared to data measured using the indirect ISO 10848 shielding&#13;
method. Recommendations are made on how appropriate the application of ISO 15712 is for this type of hybrid assembly.</abstract>

    <title language="deu">Praxisnahe, projektbasierte Lehre in der Bauakustik mit Hilfe von realen Bauobjekten</title>
    <abstract language="deu">Im Rahmen des Masterstudiengangs Bauingenieurwesen können Studierende der Ostbayerischen Technische Hochschule Regensburg einen Wahlpflichtkurs zu fortgeschrittener Bauphysik belegen, um ihr Wissen über Wärme- und Feuchteverhalten, Energieeffizienz von Gebäuden sowie Raum- und Bauakustik zu vertiefen. Im letzten Jahr wurde dieser Kurs von einer klassischen Frontalvorlesung auf eine interaktivere und praxisnähere Unterrichtsform umgestellt. Im Fokus stehen nun Gruppenarbeiten und projektbasiertes Lernen mit realen Bauprojekten. Für den Bauakustik-Teil wurde ein kürzlich errichtetes Mehrfamilienhaus in Holzbauweise als Beispielobjekt verwendet. Die Studierenden wurden in fünf Gruppen eingeteilt, die sich jeweils mit einem Aspekt des akustischen Planungsprozesses befassten: Luft- und Trittschalldämmung, Raumakustik, Fassadenschalldämmung, Geräusche von gebäudetechnischen Anlagen sowie Immissionsschutz. Jede Gruppenaufgabe war so konzipiert, dass sie Berechnungen und messtechnische Aspekte enthielt. Die Studierenden wurden durch ausgewählte Vorlesungen, Kleingruppenbetreuung und einen abschließenden "Messtag" unterstützt. Am Ende des Semesters präsentierte jede Gruppe die für die Projektaufgaben verwendeten Methoden und die Ergebnisse. Die ersten Rückmeldungen der Studierenden sind positiv, das Engagement hat spürbar zugenommen. Der praxisorientierte Ansatz impliziert, dass die Studierenden mit realen Herausforderungen konfrontiert werden, wie beispielsweise unbekannten oder fehlerhaften Daten, anspruchsvollen Messgeräten oder komplexen Vorschriften. Sie lernen, wie sie mit diesen Herausforderungen umgehen können. In diesem Beitrag werden Einzelheiten des Projekts und die bisher gesammelten Erfahrungen vorgestellt.</abstract>

    <title language="eng">Experimental study on using transient excitation signals in the prediction of sound pressure levels from building services according to EN 12354-5 and EN 15657</title>
    <abstract language="eng">EN 12354-5:2023 describes a calculation procedure to predict the sound pressure levels from building service equipment. 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.</abstract>

    <title language="eng">The Sound Reduction Index of Homogeneous Building Elements according to Annex B of ISO 12354-1 – Discussion and Proposal for Changes</title>
    <abstract language="eng">Annex B of ISO 12354-1:2017 describes a procedure for the calculation of the frequency-dependent sound reduction index of homogeneous building elements such as concrete floors or masonry walls. With the introduction of EN 12354-5:2023 and an upcoming change in DIN 4109-2 regarding the calculation of sound levels due to service equipment, it is anticipated that the practical relevance and usage of Annex B will increase in the future. For this reason, the procedure has recently been investigated by an informal working group of academics from several German universities. It was found that Annex B contains some errors, missing references, and ambiguities in the calculation procedure. Based on these discussions, some changes were proposed to the committee responsible for the standard (CEN/TC 126/WG 2). While the general calculation procedure was left unchanged, the proposed changes focus on the influence of shear deformation, the radiation factor for free waves, a moving average function to limit the variability in the coincidence region, and the calculation examples provided in the annex. This contribution provides an overview of the procedure, presents some background information on the underlying theory, and discusses the proposed changes.</abstract>

    <title language="eng">Modifying a Wall Transmission Suite to Measure Diffuse Field Sound Absorption Coefficients – A Case Study</title>
    <abstract language="eng">The determination of the diffuse field sound absorption coefficient is carried out in reverberation chambers that comply with the requirements of the corresponding standard, ISO 354. No such chamber exists at OTH Regensburg University of Applied Sciences, but a new wall transmission suite according to ISO 10140 is available. This student project investigates the possibility of using the wall transmission suite to measure absorption coefficients for teaching and research purposes.To assess the suitability of the room, the diffusivity was evaluated using the standard deviation of both the reverberation times and the equivalent continuous sound pressure levels at multiple positions within the room. These results, along with a comparison with expected values for a diffuse sound field, guided the design of reflector panels to introduce diffuse reflections. The implementation features acrylic (PMMA) as the primary material in combination with dense viscoelastic damping sheets, resulting in a low vibration solution. Suspended from the ceiling of the chamber, these improved the diffusivity of the sound field, making the room suitable for absorption measurements across a broad frequency range.</abstract>

    <title language="eng">Inverse Acoustic Characterization of Rigid Porous Media using Artificial Neural Networks</title>
    <abstract language="eng">Porous sound absorbers can be described by the isotropic Biot model, and its fluid phase can be represented by the Champoux-Allard model. To apply these models to a given absorber material, the five acoustical and the four mechanical material parameters must be known. The direct measurement of these parameters is complex and requires cost-intensive measurement equipment. Current inverse methods to obtain these material parameters solve an optimization problem, trying to fit the absorption or impedance curve of the material model to the impedance tube measurement data. Solving this optimization problem, i.e. finding the global minimum, is not guaranteed in an acceptable amount of time, as the optimization problem possesses a multitude of local minima. This work proposes an alternative, data driven approach using artificial neural networks to obtain the material parameters necessary for the characterization of open porous materials. The approach only requires the results of standard impedance tube measurements. The characterization of rigid- and elastic frame materials has been investigated. The datasets were generated using the rigid and elastic frame models for porous absorbers. The approach shows good results for impedance curves generated by the analytical models, the validation with real-world impedance tube measurement data is currently under investigation.</abstract>

    <title language="eng">Guide to calculating airborne sound transmission in buildings</title>
    <abstract language="eng">In recent years, the science and engineering for controlling sound transmission in buildings have shifted from a focus on individual assemblies such as walls or floors, to a focus on performance of the complete system. Standardized procedures for calculating the overall transmission, combined with standardized measurements to characterize sub-assemblies, provide much better prediction of sound transmission between adjacent indoor spaces. The International Standards Organization (ISO) has published a calculation method, ISO 15712-1 that uses laboratory test data for sub-assemblies such as walls and floors as inputs for a detailed procedure to calculate the expected sound transmission between adjacent rooms in a building. This standard works very well for some types of construction, but to use it in a North American context one must overcome two obstacles – incompatibility with the ASTM standards used by our construction industry, and low accuracy of its predictions for lightweight wood or steel frame construction. To bypass limitations of ISO 15712-1, this Guide explains how to merge ASTM and ISO test data in the ISO calculation procedure, and provides recommendations for applying extended measurement and calculation procedures for specific common types of construction. This Guide was developed in a project established by the National Research Council of Canada to support the transition of construction industry practice to using apparent sound transmission class (ASTC) for sound control objectives in the National Building Code of Canada (NBCC). However, the potential range of application goes beyond the minimum requirements of the NBCC – the Guide also facilitates design to provide enhanced sound insulation, and should be generally applicable to construction in both Canada and the USA. This publication contains a limited set of examples for several types of construction, to provide an introduction and overview of the ASTC calculation procedure. Additional examples and measurement data can be found in the companion documents to this Guide, namely NRC Research Reports RR-333 to RR-337. Furthermore, the calculation procedure outlined and illustrated in this Guide is also used by the software web application soundPATHS, which is available for free on the website of the National Research Council of Canada (see the references in Section 7 of this Guide for access details).&#13;
Au cours des dernières années, les scientifiques et les ingénieurs ont fait porter leurs efforts en matière d’atténuation de la transmission du son dans les bâtiments davantage sur le rendement du système dans sa totalité que sur les ensembles de construction individuels. Les méthodes normalisées de calcul de la transmission globale, combinées à des mesures normalisées de caractérisation des sous-ensembles, permettent de mieux prédire la transmission du son entre des espaces intérieurs adjacents. L’Organisation internationale de normalisation (ISO) a publié une méthode de calcul, la norme ISO 15712-1, qui utilise des données d’essai en laboratoire pour les sous-ensembles, comme les murs et les planchers, comme données d’entrée en vue d’une méthode détaillée de calcul de la transmission du son prévue entre des pièces adjacentes dans un bâtiment. Cette norme fonctionne très bien pour certains types de construction, mais pour l’utiliser dans un contexte nord-américain, il faut surmonter deux obstacles – l’incompatibilité avec les normes ASTM utilisées par notre industrie de la construction et la faible exactitude de ses prévisions pour la construction à ossature de bois ou d’acier légère. Pour contourner les limites de la norme ISO 15712-1, le présent guide explique comment fusionner les données d’essai de l’ISO et de l’ASTM dans la méthode de calcul de l’ISO, et formule des recommandations relativement à l’application de méthodes élargies de mesure et de calcul pour des types de construction courants. Le présent guide a été élaboré dans le cadre d’un projet mis sur pied par le Conseil national de recherches du Canada afin d’appuyer la transition de la pratique de l’industrie de la construction vers l’utilisation d’un indice de transmission du son apparent (ITSA) satisfaisant aux objectifs de réduction rigoureux du Code national du bâtiment du Canada (CNBC). Toutefois, l’éventail potentiel d’applications va au-delà des exigences minimales du CNBC – le Guide facilite aussi une conception visant à améliorer l’insonorisation et devrait s’appliquer de façon générale à la construction tant au Canada qu’aux États-Unis. La présente publication contient un ensemble limité d’exemples pour plusieurs types de construction, afin de fournir une introduction et un aperçu de la méthode de calcul de l’ITSA. On trouvera d’autres exemples et données de mesure dans les documents d’accompagnement du présent guide, à savoir, les rapports de recherche RR-333 à RR-337 du CNRC. De plus, la méthode de calcul décrite et illustrée dans le présent guide est également utilisée par l’application Web soundPATHS, disponible gratuitement sur le site Web du Conseil national de recherches du Canada (voir les références à la section 7 du présent guide pour les détails d’accès).</abstract>

    <title language="eng">Apparent sound insulation in wood-framed buildings</title>
    <abstract language="eng">This Report presents the results from substantial experimental studies of sound transmission, together with an explanation of calculation procedures to predict the sound transmission between adjacent spaces in a building with wood-framed walls and floors. This Report presents two types of experimental data for wood-framed constructions: - Test data for direct sound transmission through typical wood-framed wall assemblies and wood-framed floor assemblies, plus a summary of trends for such constructions and references to compilations of additional data - Test data for flanking sound transmission measured following the procedures of ISO 10848 for coupled wall/floor junctions and wall/wall junctions Worked examples for calculating the apparent sound transmission class (ASTC) rating between adjacent dwelling units are presented to illustrate how the experimental data can be applied.</abstract>
