“…Associating sounds directly with cell locations can be considered a case of data sonification [4]. In addition to cell-tone associations, the relative location of each cell with respect to a listener can also be beneficial to data exploration via sound spatialization, in what is known as auralization [22]. Whereas the mapping of cells onto sounds is arbitrary and offer limited difficulty from the software development point of view, correct spatialization of audio sources is difficult, especially in the near-field, i.e., when "The acoustic field is so close to an extended source that the effects of the source size are manifest in measurements" [23].…”

We present a Virtual Reality (VR) tool for exploration of three-dimensional cellular automata. In addition to the traditional visual representation offered by other implementations, this tool allows users to aurally render the active (alive) cells of an automaton in sequence along one axis or simultaneously create melodic and harmonic textures, while preserving in all cases the relative locations of these cells to the user. The audio spatialization method created for this research can render the maximum number of audio sources specified by the underlying software (255) without audio dropouts. The accuracy of the achieved spatialization is unrivaled since it is based on actual distance measurements as opposed to coarse distance approximations used by other spatialization methods. A subjective evaluation (effectively, self-reported measurements) of our system (n=30) indicated no significant differences in user experience or intrinsic motivation between VR and traditional desktop versions (PC). However, participants in the PC group explored more of the universe than the VR group. This difference is likely to be caused by the familiarity of our cohort with PC-based games.

“…In tracing the propagation of thousands, even millions, of rays and their interaction with the surfaces in a complex geometry, the room acoustic response can be estimated. Through such simulations, and subsequent "auralization" of the simulated room acoustic, it is then possible to render audible the acoustics of a computer simulated space [53,54]. While employed in the acoustic design of buildings [55,56], the auralization of simulated room acoustics is also at the centre of high quality virtual reality simulations which have been used, in, e.g., multimodal perception research [57,58] and historical reconstructions [59][60][61].…”

Spatial cognition is a daily life ability, developed in order to be able to understand and interact with our environment. Even if all the senses are involved in mental representation of space elaboration, the lack of vision makes it more difficult, especially because of the importance of peripheral information in updating the relative positions of surrounding landmarks when one is moving. Spatial audio technology has long been used for studies of human perception, particularly in the area of auditory source localisation. The ability to reproduce individual sounds at desired positions, or complex spatial audio scenes, without the need to manipulate physical devices has provided researchers with many benefits. We present a review of several studies employing the power of spatial audio virtual reality for research in spatial cognition with blind individuals. These include studies investigating simple spatial configurations, architectural navigation, reaching to sounds, and sound design for improved acceptability. Prospects for future research, including those currently underway, are also discussed.

Este artigo aborda a validação dos resultados de simulação do código computacional de acústica de salas do Software RAIOS 7. O programa calcula as respostas impulsivas mono e biauriculares (RIR e BRIR), bem como os parâmetros de qualidade acústica em um dado recinto, para pares especificados fonte-receptor. De modo a validar as respostas impulsivas monoauriculares e o cálculo dos parâmetros acústicos, resultados de simulação são comparados com resultados de outros programas, bem como com dados de medição na sala, anteriormente publicados. A sala simulada é uma das utilizadas na última intercomparação internacional de simuladores. Mostra-se que o código computacional em estudo apresentou desvios similares aos demais programas. Para validar as respostas impulsivas biauriculares utilizam-se testes de articulação. São realizados ensaios de inteligibilidade em cinco salas de aula de diferentes dimensões. As mesmas salas são modeladas no código computacional de modo a gerar as respostas impulsivas biauriculares para pares fonte-receptor posicionados tal como na sala real. Os mesmos sinais sonoros utilizados nos testes reais são então convoluídos com as respostas impulsivas biauriculares simuladas, gerando aurilizações. Testes de articulação são, finalmente, realizados e os seus resultados comparados com os testes conduzidos nas salas reais, indicando erros menores que 5%.
