Повний текст джерелаRoom acoustics is the science devoted to study sound propagation in enclosures where the sound conduction medium is bounded on all sides by walls, ceiling and floor. The acoustic information of any room, the so-called impulse response, is expressed in terms of the acoustic field as a function of space and time. The analytical formulation of the sound variables distribution is, in general, extremely hard to obtain and there only exist solutions of very simple and unrealistic scenarios. Therefore the use of computers for solving this type of problems has emerged as a proper alternative to calculate impulse responses. In this Thesis we focus on the use of the ray-based methods to compute impulse responses. More precisely, we present the design and implementation of a sound ray tracing engine that computes the impulse response in any given environment not only for the pressure but also for the velocity vector of the acoustic field. With this extra information we have all the necessary data to model the propagation of sound and we can then naturally spatialize the sound to any speakers layout. This research contributes to the main aspects in the computation of impulse responses using a ray-based approach. The presented ray tracing engine includes a method developed to apply the analytical solution for the Acoustic Bidirectional Reflectance Distribution Function (A-BRDF) in the Vector Based Scattering Model (VBS), which reduces dramatically the computational cost.

Повний текст джерелаThe study of room acoustics is linked to the importance of sound inside a room, so the architectural characteristics of the internal space determine the acoustic behavior. To get better acoustics of a room there are computational methods that simulate the acoustic behavior of a room before his execution, providing the prediction of the simulated environment behavior from the acoustic point of view. The acoustic parameters of the resulting acoustic simulations as Reverberation Time, Initial Decay Time, Clarity, Sharpness and Speech Transmission Index, are responsible for identifying the acoustic conditions of the geometric model of a classroom. This geometric model used as sample classrooms of different types of municipal schools in Santa Maria - RS, with the aim of developing a classroom typology for the music teaching from virtual acoustic models using computing simulation. Geometric models of classrooms for teaching music were developed using as input data, dimensions, shapes and elements usually used in these environments and developed representative virtual acoustic models these virtual classrooms, in which were measured acoustic parameters related to the reverberation time from the impulse response of the acoustic models of virtual rooms. We analyzed the experimental results and simulated with and without furniture for the acoustic parameters, and these comparisons were related to the values of JND (Just Noticeable Difference) near the standard tolerance according to ISO 3382/2009 with normalized values of 500 Hz to 1000 Hz. A geometric study was developed based on Bolt (1946) which defined the appropriate geometric measures of the room. Thus, a functional typology was originated which meets the architectural acoustic requirements and the initial proposal of presenting a music classroom typology providing an environment with acoustic quality, according to Law number 11.769/2008 that inserts education music in schools on a mandatory basis.
O estudo da acústica de salas está vinculado à importância do som dentro de um recinto, logo, as características arquitetônicas do espaço interno determinam seu comportamento acústico. Para buscar melhores condições acústicas de um recinto disponibilizam-se métodos computacionais que simulem o comportamento acústico de uma sala, antes de sua execução, proporcionando a previsão de comportamento do ambiente simulado do ponto de vista acústico. Os parâmetros acústicos resultantes das simulações acústicas, como: Tempo de Reverberação, Tempo de Decaimento Inicial, Clareza, Definição e o Índice de Transmissão da Fala são responsáveis pela identificação das condições acústicas do modelo geométrico de uma sala de aula. Este modelo geométrico utilizou como amostra as salas de aula das diferentes tipologias de escolas da rede estadual de educação de Santa Maria - RS, com o objetivo de desenvolver uma tipologia de sala de aula, para o ensino da música, a partir de modelos acústicos virtuais utilizando-se simulação computacional. Foram desenvolvidos modelos geométricos de salas de aula para o ensino da música utilizando-se como dados de entrada, dimensões, formatos e elementos, usualmente utilizados nestes ambientes, e desenvolvidos modelos acústicos virtuais representativos destas salas, aos quais foi feita uma avaliação dos parâmetros acústicos relacionados ao tempo de reverberação, partindo-se da resposta impulso dos modelos acústicos virtuais das salas. Foram analisados resultados experimentais e simulados na situação sem mobília e com mobília, para os parâmetros acústicos, e essas comparações foram relacionadas com os valores de JND (em inglês Just Noticeable Difference) padronizadas as margens de tolerância, de acordo com a ISO 3382/2009, com valores normalizados de 500 Hz a 1000 Hz. Também foi desenvolvido um estudo geométrico, a partir de Bolt (1946), que definiu as medidas geométricas adequadas da sala. Com isto, originou-se uma tipologia funcional, observando as exigências acústicas arquitetônicas, cumprindo a proposta inicial de apresentar uma tipologia de sala de aula, para a música, a fim de proporcionar um ambiente com qualidade acústica, atendendo a Lei nº 11.769/2008, que insere o ensino da música nas escolas, de forma obrigatória.

Повний текст джерелаEn aquesta Tesi hem centrat el nostre anàlisis en els mètodes basats en el comportament ondulatori dins del domini temporal. Més concretament, estudiem en detall les formulacions més importants del mètode de Diferències Finites, el qual s'utilitza en moltes aplicacions d'acústica de sales, i el recentment proposat mètode PseudoEspectral de Fourier. Ambdós mètodes es basen en la formulació discreta de les equacions analítiques que descriuen els fenòmens acústics en espais tancats.
Aquesta obra contribueix en els aspectes més importants en el càlcul numèric de respostes impulsionals: la propagació del so, la generació de fonts i les condicions de contorn de reactància local.
Room acoustics is the science concerned to study the behavior of sound waves in enclosed rooms. The acoustic information of any room, the so called impulse response, is expressed in terms of the acoustic field as a function of space and time. In general terms, it is nearly impossible to find analytical impulse responses of real rooms. Therefore, in the recent years, the use of computers for solving this type of problems has emerged as a proper alternative to calculate the impulse responses.
In this Thesis we focus on the analysis of the wavebased methods in the timedomain. More concretely, we study in detail the main formulations of FiniteDifference methods, which have been used in many room acoustics applications, and the recently proposed Fourier PseudoSpectral methods. Both methods are based on the discrete formulations of the analytical equations that describe the sound phenomena in enclosed rooms.
This work contributes to the main aspects in the computation of impulse responses: the wave propagation, the source generation and the locallyreacting boundary conditions.
