Technical Note: Prediction Models of Airborne Sound Insulation of Multilayer Materials with Viscoelastic Thin Sheets
2008
The growing introduction of new insulation materials in building acoustics has caused an increase of the importance of the prediction tools. Appropriate simulations allow strictly necessary laboratory measurements to be identified. In this way, costs are reduced. The demands of new legislation has resulted in the appearance of various software designed to facilitate prediction. The prediction models are based on different hypotheses: adaptation of impedances, spatial behaviour of spectral components, statistical energy distribution, the Finite Element Method (FEM), etc. Each of these models and methods offer advantages and contain limitations. In this paper, different models for prediction…
Multi-sensory approaches to (audio) describing the visual arts
2012
Making art accessible to blind patrons requires the ability to convey explicit and implicit visual messages through non-visual forms. Audio description is often seen as the best way to offer visual texts to blind people; however, one may query whether words alone are sufficient to convey the subtleties of art and to transport the emotional charge such works offer. It is a fact that the dialogue between words and touch may allow these particular “readers” to “see” art in its tangible forms, but perhaps more is needed if one is to give them the opportunity to live the art experience to the full. This article discusses different multi-sensory approaches to making art available to visually impa…
New Acoustic Test Chambers at the University of Palermo
2008
Acoustic test chambers at the University of Palermo have been completed after a design optimization of existent building structures. A unique building houses five reverberation chambers, differently coupled each other in order to achieve a large flexibility on testing procedures, and offices for the staff. Main measurements offered to national and international standards include determination of sound power, sound insulation and sound absorption. Reverberation chambers present peculiar geometries in order to achieve the desidered sound fields. Chambers structure and layout within the whole building, housing all the acoustic facilities, has been designed in order to achieve strong sound insu…
Technical Note: Airborne Sound Insulation of Hollow Brickwork
2007
This paper reports on the uncertainty of in situ measurements of the airborne sound insulation of hollow-brick walls in different housing plans, with emphasis on the influence of expansion joints. The mean and standard deviation of multiple measurements are obtained, which show significant differences in insulation values despite the fact that the same construction was used in each case.
Aplicaciones didácticas del lenguaje Soundpainting en diferentes ámbitos educativos: una herramienta para la creación en tiempo real
2014
El lenguaje de signos Soundpainting es un sistema para la creación en tiempo real basado en la interacción gestual entre un compositor/creador llamado soundpainter y un grupo de intérpretes que responden a los gestos creando material sonoro, visual o de movimiento. El objetivo de esta investigación ha sido analizar y describir cómo se ha aplicado este lenguaje en tres ámbitos educativos diferentes. En el marco teórico se analizan los antecedentes en lo que a creación en tiempo real se refiere para después centrarnos en el estado de la cuestión, revisando la bibliografía en relación a estudios recientes sobre Soundpainting en el aula de música. Partiendo de la metodología cualitativa se sele…
Development of the Happiness Index in a country
2016
[EN] In this paper, a Happiness Index is built through the Human Dignity Respect Index which is explained by Author (2014). The index is created using three main values: development, freedom and equality. But the equality is explained by solidarity, justice and peace. Then, the Happiness Index is developed with this five concepts. The aim of this paper is to obtain the minimum quantitative variables to explain these values as well as to obtain a generic formula, which allows measuring the happiness of a country/region. The term “generic” is introduced because this formula could be extrapolated to any country. The variables to obtain the Development Index are health (Life Expectancy at birth…
Componiendo con Soundpainting en el aula de música. Un estudio de casos colectivo sobre creación sonora colaborativa
2021
Soundpainting (SP) es el lenguaje de signos creado por Walter Thompson para la creación sonora en tiempo real. Se basa en la comunicación y la interacción, mediante la producción de gestos, entre un compositor (soundpainter) y un grupo de intérpretes (performers). Este diálogo genera un material sonoro y visual para poder crear de manera colaborativa composiciones de arte multidisciplinar. Esta investigación ha analizado el desempeño creativo de diferentes grupos de alumnos de educación primaria y secundaria al usar el lenguaje SP como recurso para la creación sonora en tiempo real, describiendo sus experiencias de colaboración creativa. Desde un enfoque cualitativo, se ha optado por elegir…
