Dissertations / Theses on the topic 'Airborne sound insulation'

Describing planned acoustic design by single number ratings yields a weak link to the subjective event, especially when the single number ratings are interpreted by others than experienced acousticians. When developing infrastructure, tools for decision making needs to address visual and aural perception. Visual perception can be addressed using game engines and this has enabled the establishment of tools for visualizations of planned constructions in virtual reality. Audio engines accounting for sound propagation in the game engine environment are steadily developing and have recently been made available. The aim of this project is to simulate airborne sound insulation by extending the support of recently developed audio engines directed towards virtual reality applications. The case studied was airborne sound insulation between two adjacent rooms in a building, the sound transmitted to the receiving room through the building structure resulting from sound pressure exciting the structural elements in the adjacent source room into vibration. The receiving room composed modelled space in the game engine Unreal Engine and Steam Audio was the considered audio engine. Sound transmission was modelled by filtering based on calculations of transmission loss via direct and flanking paths using the model included in the standard EN 12354-1. It was verified that the filtering technique for modelling sound transmission reproduced attenuations in correspondence with the predicted transmission loss. Methodology was established to quantify the quality of the audio engine room acoustics simulations. A room acoustics simulation was evaluated by comparing the reverberation time derived from simulation with theoretical predictions and the simulated reverberation time showed fair agreement with Eyring’s formula above its frequency threshold. The quality of the simulation of airborne sound insulation was evaluated relating the sound field in simulation to insulation classification by the standardized level difference. The spectrum of the simulated standardized level difference was compared with the corresponding sound transmission calculation for a modelled scenario. The simulated data displayed noticeable deviations from the transmission calculation, caused by the audio engine room acoustics simulation. However, the simulated data exhibited cancellation of favourable and unfavourable deviations from the transmission calculation resulting in a mean difference across the spectrum below the just noticeable difference of about 1 dB. Single number ratings was compared and the simulated single number rating was within the standard deviation of how the transmission model calculates predictions for a corresponding practical scenario measured in situ. Thus, the simulated data shows potential and comparisons between simulated data, established room acoustics simulation software and in situ measurements should further be made to deduce whether the deviations entails defects in the airborne sound insulation prediction or is an error imposed by the audio engine room acoustics simulation.

Understanding uncertainty is an important part of any scientific measurement process and the ability to evaluate and understand uncertainty is a requirement of the International Standards for quality control. The basic uncertainties relating to the measurement of airborne sound insulation in the field can be assessed using the methods in BS5725. However, identifying the components that contribute to the total variability is beyond the scope of the standard and more detailed information requires a more advanced approach. Recent developments in the “Guide to the expression of uncertainty in measurement” (GUM) suggest an approach can be used where identification of the input variables and their likely contribution will result in a solution that can be modelled providing enough information is available. However, recent research on uncertainty in sound insulation using GUM has identified problems involving the correlation between frequency bands, which leads to an overestimate of uncertainty. An empirical approach is used in this thesis, which incorporates advanced analysis of variance (ANOVA) and a specific model called Gauge Repeatability and Reproducibility (GRR). It enables the components of variance in the measurement system to be partitioned and provides an estimate of their contribution. In addition, ANOVA highlights any interaction between factors. In the GRR, carried out on a lightweight timber floor and a heavyweight concrete floor, significant interaction was detected between the operator and part. Good agreement is obtained in the repeatability and reproducibility calculated for each construction and the samples are combined with measurements of test elements that provide a wider range of sound insulation performance. The uncertainty associated with the instrumentation, operator, interaction and part are calculated in each case. It is shown that the interaction component is important and should be contained in any approach evaluating uncertainty. Further evidence reveals that the total uncertainty in the measurement process is dependent on the construction being measured.

This research thesis involves the measurement of the airborne sound insulation of road traffic noise barriers, with the goal of gaining a more in depth understanding of the factors that influence noise barrier performance. A measurement system is developed, based on EN 1793-6:2012, to quantify the airborne sound insulation of a noise barrier in situ. Validation testing is performed to ensure that the system meets the requirements of EN 1793-6:2012. MATLAB code is developed, incorporating all of the signal processing tasks into a single graphical user interface. The measurement system is then used to measure the airborne sound insulation of eight existing traffic noise barriers located around Auckland, New Zealand. The results from the Auckland field tests show that consistent single number ratings of airborne sound insulation can be achieved on different samples of the same noise barrier. The presence of air gaps and hidden defects will degrade the acoustic performance of a noise barrier, most significantly at the high frequencies. The comparison of single number ratings calculated with differing measurement frequency ranges is discussed, and some comments are made on the measurement standard itself.

In this research some kinds of masonry walls have been used as internal divisions in three Brazilian dwelling buildings to determine the airborne sound reduction, by experimental tests in field and computer simulations. The masonry walls studied are composed by massive bricks, bored ceramic blocks (6 and 4 holes) and structural (7 and 10 MPa), with mortar lining in both sides. The acoustic evaluations, in field, were accomplished according to the international rules ISO 140 part 4, ISO 717 part 1 and ISO 354. The determination of the airborne sound reduction among places it was accomplished from a direct and indirect sound transmission of constructive elements of the edifications, according to the EN 12354 rule part 1 and using a commercial computer program. The mainly results of this research showed the weighted values of the level standard difference (DnT,w) vary from 37 to 44 decibels to the evaluated walls. It was also observed the difference of 2 dB among the weighted values of the level standard difference (DnT,w) and the apparently sound reduction (R w). Almost all the masonry walls evaluated reached the minimum recommended values by the NBR 15575. In general, it happened a relation between the experimental results and the computer simulations, mainly with the weighted values relation and the isolation curves of the structural masonry walls. The computer simulation of the airborne sound transmission can be a good project tool, besides the initial datas don t represent properly the masonry material components evaluated, due to the national datas more complete and precise.
Neste trabalho são avaliadas alguns tipos de paredes de alvenaria utilizadas como divisórias internas em três edifícios habitacionais brasileiros para determinar a redução sonora aérea, através de ensaios experimentais em campo e de simulações computacionais. As paredes de alvenaria estudadas são compostas por tijolos maciços, blocos cerâmicos furados (6 e 4 furos) e estruturais (7 e 10 MPa), com revestimento de argamassa em ambos os lados. As avaliações acústicas, em campo, foram realizadas de acordo com as normas internacionais ISO 140 parte 4, ISO 717 parte 1 e ISO 354. A determinação da redução sonora aérea entre ambientes foi realizada a partir da transmissão sonora direta e indireta dos elementos construtivos das edificações, conforme a norma EN 12354 parte 1 e utilizando um programa computacional comercial. Os resultados principais desta pesquisa mostram que os valores ponderados da diferença padronizada de nível (DnT,w) variaram de 37 a 44 decibéis para as paredes avaliadas. Também, foi observada uma diferença de 2 dB entre os valores ponderados da diferença padronizada de nível (DnT,w) e do índice de redução sonora aparente (R w). Praticamente, todas as amostras de paredes de alvenaria avaliadas atingiram os valores mínimos de desempenho recomendados pela NBR 15575. Em geral, ocorreu uma boa correlação entre os resultados experimentais e as simulações computacionais, principalmente com relação aos valores ponderados e as curvas de isolamento das paredes de alvenaria estrutural. A simulação computacional da transmissão sonora aérea pode ser uma boa ferramenta de projeto, apesar dos dados de entrada não representarem fielmente as propriedades dos materiais componentes das alvenarias avaliadas, devido à carência de dados nacionais mais completos e precisos.

[ES] El control de ruido ambiental es una preocupación de primera magnitud para las sociedades avanzadas, debido a los problemas derivados que ocasionan en la salud de los ciudadanos. Una de las soluciones más extendidas para el control del ruido en su fase de transmisión en la utilización de pantallas acústicas. La aparición de nuevos materiales formados por redes de dispersores acústicos aislados, denominados cristales de sonido, está revolucionando el campo del apantallamiento acústico, posibilitando el avance tecnológico de esta área. Así, en los últimos años, las pantallas acústicas basadas en cristales de sonido se han posicionado como una alternativa viable a las pantallas acústicas tradicionales, puesto que ofrecen múltiples ventajas frente a las soluciones actuales. En el presente trabajo se muestra primeramente una recopilación de los avances realizados en el campo del apantallamiento acústico mediante esta tipología de pantallas. No obstante, aún existen líneas de investigación abiertas en esta área, que es necesario abordar para conseguir el objetivo de aplicar esta tecnología como atenuadores de sonido en las infraestructuras de transporte. Durante el periodo de formación de la doctoranda, se ha trabajado en algunas de las líneas de investigación activas en este campo del apantallamiento acústico. Una de estas investigaciones condujo al descubrimiento de interferencias entre los efectos de la resonancia y la dispersión múltiple de los cristales de sonido cuando estos efectos se producen en rangos de frecuencia cercanos. También hemos diseñado un nuevo dispositivo de reducción de ruido basado en cristales de sonido, utilizando herramientas de optimización multiobjetivo, que permitan apantallar y reflejar de forma difusa el ruido. El empleo de esta nueva herramienta de diseño identificó la necesidad de realizar un estudio comparativo de los métodos de simulación más utilizados para estimar el rendimiento de los dispositivos basados en cristales de sonido. Por último, hemos realizado un estudio psicoacústico para determinar la percepción de la reducción de molestia que proporcionan las pantallas acústicas basadas en cristales sonido y las barreras tradicionales, determinando si los parámetros objetivos que evalúan su rendimiento coinciden con la respuesta subjetiva de los usuarios.

Durant el període de formació de la doctoranda, s'ha treballat en algunes de les línies d'investigació actives en este camp de l'apantallament acústic. Una d'estes investigacions va conduir al descobriment d'interferències entre els efectes de la ressonància i la dispersió múltiple dels cristals de so quan estos efectes es produïxen en rangs de freqüència pròxims.

L'ús d'esta nova ferramenta de disseny va identificar la necessitat de realitzar un estudi comparatiu dels mètodes de simulació més utilitzats per a estimar el rendiment dels dispositius basats en cristals de so. Finalment, hem realitzat un estudi psicoacústic per a determinar la percepció de la reducció de molèstia que proporcionen les pantalles acústiques basades en cristals so i les barreres tradicionals, determinant si els paràmetres objectius que avaluen el seu rendiment coincidixen amb la resposta subjectiva dels usuaris.
[EN] Control of environmental noise is a major concern for advanced societies because of the resulting problems for citizens' health. One of the most widespread solutions for controlling noise in its transmission phase is the use of acoustic screens. The emergence of new materials made up of arrays of isolated acoustic scatterers, called sonic crystals, is revolutionizing the field of acoustic screening. In recent years, acoustic screens based on sonic crystals have positioned themselves as a viable alternative to traditional acoustic screens, as they offer multiple advantages over current traditional solutions. This Doctoral dissertation compiles the advances in the field of acoustic screening using this type of sonic crystals. However, there is still active research in this area which needs to be addressed and studied in order to apply this technology as noise reduction devices in transport infrastructures. Therefore, during the PhD student's training period, we have researched the acoustic phenomena produced by isolated scatterers in order to better understand the physical phenomena behind the lasts designs of this type of screen. One of these researches led to the discovery of interferences between the effects of resonance and multiple scattering of sonic crystals when occurring in nearby frequency ranges. Also we have designed a new noise reduction device based on sonic crystals, using multi-objective optimization tools, which would block and diffuse the noise. This new designing tool identified the need for a comparative study of the most commonly used simulation methods to estimate the performance of devices based on sonic crystals. Finally, we have carried out a psychoacoustic study that determined the perception of the annoyance reduction provided by acoustic screens based on sonic crystals and traditional barriers, determining whether the objective parameters that evaluate their performance match to the subjective response of the users.

This thesis is to study the sound insulation and sound absorption of acoustic materials which is used to buildings and roadway engineering. In order to understanding the acoustic insulation materials property, the acoustic measurement experiments must be carried out in the standard laboratory . The measurement values are sound transmission loss and the sound absorption coefficients with a reverberation room method or the impedance tube method. Also, in this thesis quote the norm prCEN/TS 1793 Road Traffic Noise Reducing Devices-Test Method for determining the acoustic performance-Part 5:Intrinsic characteristics-In situ values of sound reflection and airborne sound insulation , we can confer the material effect which is installed actually . The in-situ measurement is an analysis that produce an impulse response with the temporal signal, use a maximum-length sequence (MLS) as the standard test signal , we also join the Adrienne temporal window and signal subtraction technique to calculate the values of sound insulation index and sound absorption. The comparison and discussion are finished with the results of experimentation in laboratory . We can understand the effects of reducing noise that the materials is at the scene and the laboratory, and also can get the relative relation between the both results.

No
Recent progress in the development of European standards has allowed the in situ testing of roadside noise barriers. CEN/TS 1793-5 describes a test method using maximum length sequences (MLS) for the characterisation of airborne sound insulation. However, many barriers are tested according to a laboratory standard, EN 1793-2, based on measurements carried out in reverberant chambers and in the case of timber barriers with a relatively low airborne sound insulation it is not clear to what extent the results of the two tests compare. The paper describes the results of tests carried out using both methods. Six samples of timber barrier were compared including single-leaf and double-leaf constructions and single-leaf constructions with an absorptive core. Very good agreement was found especially when account was taken of the valid frequency range in each test method. The results open up the possibility of routinely evaluating the performance of timber barriers at the roadside where build quality can be variable and there are concerns that the acoustic performance may not match that obtained under laboratory test conditions where typically the barrier is more carefully constructed.

Yes
The in situ measurement of the airborne sound insulation, as outlined in EN 1793-6:2012, is becoming a common means of quantifying the performance of road traffic noise reducing devices. Newly installed products can be tested to reveal any construction defects and periodic testing can help to identify long term weaknesses in a design. The method permits measurements to be conducted in the presence of background noise from traffic, through the use of impulse response measurement techniques, and is sensitive to sound leakage. Factors influencing the measured airborne sound insulation are discussed, with reference to measurements conducted on a range of traffic noise barriers located around Auckland, New Zealand. These include the influence of sound leakage in the form of hidden defects and visible air gaps, signal-to-noise ratio, and noise barrier height. The measurement results are found to be influenced by the presence of hidden defects and small air gaps, with larger air gaps making the choice of measurement position critical. A signal-to-noise ratio calculation method is proposed, and is used to show how the calculated airborne sound insulation varies with signal-to-noise ratio. It is shown that the measurement results are influenced by barrier height, through the need for reduced length Adrienne temporal windows to remove the diffraction components, prohibiting the direct comparison of results from noise barriers with differing heights.
The authors would like to thank the NZ Transport Agency for sponsoring the Auckland traffic noise barrier testing work, and the Auckland Motorway Alliance for assisting with access to the test sites.

Ao longo dos anos a exigência em relação à envolvente dos edifícios tem vindo a aumentar, devido aos níveis de conforto mais elevados que a sociedade tem vindo a requerer. Devido à necessidade de proteção do ambiente interior do ruído exterior, de qualidade do ambiente interior e de redução de consumo de energia, enquadra-se a importância do estudo da relação entre comportamento acústico e permeabilidade ao ar da envolvente de edifícios. Na prossecução do objetivo definido foi efetuada a revisão bibliográfica de estudos pertinentes para o trabalho realizado. Foram estudados dois métodos de ensaio: o ensaio de pressurização, com recurso ao equipamento Blower Door de acordo com a norma NP 13829:2000 [1], e ensaios in situ de avaliação do isolamento sonoro a sons de condução aérea da fachada, de acordo com a norma NP ISO 140-5:2009 [2]. Foram selecionados e analisados compartimentos e edifícios onde se utilizaram os métodos de ensaio previamente estudados. A seleção dos edifícios foi realizada de forma a tentar permitir os dois ensaios no mesmo edifício. Para os edifícios selecionados, foi realizada a caracterização, compilação de dados e, nalguns casos, obtenção de resultados adicionais. A partir da análise dos dados recolhidos tentou analisar-se a relação do comportamento acústico, da permeabilidade ao ar, e das características dos edifícios.
Over the years the requirements for the building envelope has been increasing due to higher levels of comfort according to society’s needs. It was due to the aim of protecting the indoor environment from the outside noise, indoor environmental quality and reduce energy consumption, that the study of the relationship between the acoustic behavior and air permeability of the buildings envelope aroused. In order to attain the objective of this study a review of studies, relevant to the theme of the work performed, was carried out. Two test methods were studied: the pressurization test, using the pressurization equipment Blower Door according to NP 13829:2000 [1], and measurements of airborne sound insulation of façades, according to EN ISO 140-5:2009 [2]. The buildings were selected so that both tests, mentioned above, were applied in the same building. For the selected buildings a characterization and compilation of data were developed, and additional results were obtained. From the analysis of the collected data and evaluated results the relationship between acoustic behavior, air permeability, and the characteristics of the buildings was studied and analyzed

O isolamento sonoro à propagação de sons aéreos entre recintos tem vindo a ser um dos requisitos que cada vez mais suscita exigência por parte dos utilizadores dos compartimentos onde se requer silêncio. O isolamento a sons aéreos deve ser um parâmetro bem analisado por parte da equipa projetista, na conceção do edifício, de forma a que na fase final da construção, aquando das medições para verificação dos índices regulamentares, não haja surpresas quanto ao eventual incumprimento dos valores definidos pela legislação nacional. Com a publicação da norma NP EN ISO 16283-1:2014 são definidos dois procedimentos diferentes de ensaio, procedimento geral e procedimento de baixa frequência. É então que surge a necessidade de esclarecer as entidades se devem ou não aplicar o procedimento de baixa frequência, o que acarreta uma alteração da legislação com vista a especificar este novo parâmetro. A investigação no âmbito deste trabalho incide na quantificação e análise do erro que pode ser cometido utilizando apenas o método geral e assim concluir acerca da necessidade de aplicação de cada um dos métodos consoante a dimensão volumétrica dos compartimentos em ensaio. Este ponto coloca um vazio na legislação nacional uma vez que esta não prevê enquadramento para o método de baixa frequência e a norma apenas prevê o referido enquadramento sempre que os volumes dos compartimentos em ensaios sejam inferiores a 25 m3.
The sound insulation at the propagation of airborne sounds between rooms has been one of the requirements that increasingly raises demand from users of compartments which require silence. The insulation to airborne sounds must be a very well-studied parameter by the designer team in the building design, so that in the final phase of construction during the measurements to verify the legal framework there will be no surprises as to any breach of values defined by national legislation. With the publication of the standard NP EN ISO 16283-1:2014 there were defined two different test procedures, the general procedure and the low frequency procedure. It is then that emerges the need to clarify the entities whether or not to apply the low frequency procedure, which entails a change in legislation to specify the new parameter. The research in this work focuses on the quantification and analysis of the error that can be made using only the general method and thus conclude on the need for implementation of each method according to the volumetric size of the compartments under test. This point raises a void in national law since it does not provide framework for low frequency procedure and the standard regulation only provide a framework where the volumes of compartments tests are below 25 m3.

As preocupações crescentes da sociedade atual com a poupança energética, sustentabilidade e, simultaneamente a exigência de padrões de conforto cada vez mais elevados, torna imperativo o estudo de soluções construtivas que preencham estes requisitos. A constituição da envolvente dos edifícios poderá ter um grande impacto quer na poupança energética quer no conforto no seu interior. Sendo as paredes de fachada o elemento que ocupa tradicionalmente uma maior área da envolvente opaca, é nele que se poderá atuar. O isolamento térmico exterior de paredes é uma solução construtiva que apresenta inúmeras vantagens, como por exemplo a manutenção da inércia térmica, a correção das pontes térmicas e a redução das condensações superficiais, tornando-o numa alternativa a ter em consideração para a envolvente de edifícios. Porém, a sua utilização não é isenta de desvantagens e limitações. A principal desvantagem da colocação de isolamento térmico pelo exterior é a sua fragilidade ao impacto e perfuração. Ora, havendo no nosso país uma tradição muito marcada na aplicação de revestimentos cerâmicos, eles podem ser usados no revestimento de paredes com isolamento térmico exterior, dando resposta às limitações da solução anterior. Tendo em vista esta hipótese, é fundamental conhecer os requisitos e ensaios de avaliação de desempenho, bem como antever as exigências que se devem impor ao sistema de isolamento térmico exterior com revestimento cerâmico. Neste trabalho é realizado, adicionalmente, o cálculo do atraso térmico e do isolamento a sons aéreos exibidos pelas soluções convencionais de isolamento térmico colocado pelo exterior e por aquelas mesmas soluções revestidas com ladrilhos cerâmicos. Assim, é possível avaliar as melhorias no desempenho térmico e acústico quando no sistema de isolamento térmico pelo exterior se aplica revestimento cerâmico.
Today’s societies concerns with energy saving, sustainability and, simultaneously, the demanding of higher standards of comfort, makes imperative the study of constructive solutions that fulfil all this requirements. The buildings’ envelope composition may have a great impact either in energy savings and interior comfort. Being the element that traditionally occupies a larger area of the opaque envelope, is there where we may act. Exterior thermal insulation of walls is a buildings’ constructive solution which presents several advantages, e.g. maintenance of the thermal inertia, correction of the thermal bridges and reduction of superficial condensation, making it an alternative to take into account for the buildings’ envelope. However, its use isn’t free of disadvantages and limitations. In fact, the main disadvantage of putting the thermal insulation in the outside is its fragility to the impact and perforation. Now, having our country a great tradition in the application of ceramic coating, it may be used as a coating for walls with exterior thermal insulation, responding to the limitations of the previous system. Having this hypothesis in mind, it’s fundamental to know the performance requirements and evaluation tests, as well as to predict the requirements to impose to the external thermal insulation with ceramic tiling. In this paper, it is done, additionally, the calculation of the thermal delay and airborne sound insulation of conventional wall solutions with external thermal insulation and for those same solutions coated with ceramic tiling. That way, it is possible to evaluate the improvements in terms of thermal and acoustical performance when it is applied ceramic coating in the external thermal insulation system.
