En el present treball de final de màster se centra en el desenvolupament d'una pantalla acústica inspirada principalment en l'anatomia humana amb l'objectiu d'abordar el problema del soroll. La recerca s'ha basat en una anàlisi sobre els fonaments del soroll, les gammes de producte existent i altres aspectes sobre la propagació del soroll amb la finalitat d'entendre i comprendre millor la naturalesa del soroll. En la fase inicial, s'ha dut a terme un estudi de camp utilitzant un sonòmetre en àrees amb nivells elevats de soroll. Això ha permès recopilar i comparar dades per a recolzar el *elfoque conceptual validant així la necessitat de dissenyar i crear solucions efectives. Posteriorment, es va realitzar una enquesta per a obtenir informació addicional. Sobre la base de totes aquestes anàlisis obtingudes en les etapes de recerca, s'ha continuat a la fase de disseny mitjançant models 3D amb la seva posterior validació amb un programari especialitzat. En aquesta etapa no sols es van prioritzar aspectes de disseny sinó també estètics i sobretot de funcionalitat assegurant la reducció del soroll i la difusió del mateix d'una forma eficaç. Així, aquest treball de recerca i desenvolupament representa un enfocament per a abordar la problemàtica del soroll a través del disseny mitjançant una forma creativa i sostenible. Els estudis de la difracció del soroll, la recerca de camp, l'enquesta i finalment el disseny 3D CAD s'han combinat per a proporcionar una solució integrada., En el presente trabajo de final de máster se centra en el desarrollo de una pantalla acústica inspirada principalmente en la anatomía humana con el objetivo de abordar el problema del ruido. La investigación se ha basado en un análisis sobre los fundamentos del ruido, las gamas de producto existente y otros aspectos sobre la propagación del ruido con el fin de entender y comprender mejor la naturaleza del ruido. En la fase inicial, se ha llevado a cabo un estudio de campo utilizando un sonómetro en áreas con niveles elevados de ruido. Esto ha permitido recopilar y comparar datos para respaldar el elfoque conceptual validando así la necesidad de diseñar y crear soluciones efectivas. Posteriormente, se realizó una encuesta para obtener información adicional. En base a todos estos análisis obtenidos en las etapas de investigación, se ha continuado a la fase de diseño mediante modelos 3D con su posterior validación con un software especializado. En esta etapa no solo se priorizaron aspectos de diseño sino también estéticos y sobre todo de funcionalidad asegurando la reducción del ruido y la difusión del mismo de una forma eficaz. Así, este trabajo de investigación y desarrollo representa un enfoque para abordar la problemática del ruido a través del diseño mediante una forma creativa y sostenible. Los estudios de la difracción del ruido, la investigación de campo, la encuesta y por último el diseño 3D CAD se han combinado para proporcionar una solución integrada., This master's thesis focuses on the development of an acoustic screen inspired mainly by the human anatomy in order to address the problem of noise. The research has been based on an analysis of noise fundamentals, existing product ranges and other aspects of noise propagation in order to better understand and comprehend the nature of noise. In the initial phase, a field study was carried out using a sound level meter in areas with high noise levels. This allowed data to be collected and compared to support the conceptual approach, thus validating the need to design and create effective solutions. Subsequently, a survey was conducted to obtain additional information. Based on all these analyses obtained in the research stages, we continued to the design phase using 3D models with their subsequent validation with specialised software. At this stage, priority was given not only to design aspects but also to aesthetic and, above all, functional aspects, ensuring effective noise reduction and noise diffusion. Thus, this research and development work represents an approach to address the noise problem through design in a creative and sustainable way. Noise diffraction studies, field research, survey and finally 3D CAD design have been combined to provide an integrated solution.

Radiant slab systems have the potential to achieve significant energy savings, yet, when applied in the ceiling (e.g., thermally activated building system) the exposed concrete may also create acoustical challenges due to the high reflectivity of the hard surface. Balancing all of the building indoor environmental quality factors is important in the design of an effective workspace for the occupants, and so we need to consider the interactions between thermal and acoustic comfort. We assessed the cooling capacity in a hydronic test chamber and the sound absorption in a reverberation chamber to study the effects, for an office room, of different coverage areas of free-hanging acoustical clouds below a radiant chilled ceiling. The cooling experiments showed that for 47% cloud coverage of the ceiling area, we measured only an 11% reduction in cooling capacity caused by the blockage of radiant exchange between the ceiling and the room. The acoustical results showed that if the cloud covered 30% of the ceiling in a private office or 50% in an open plan office, acceptable sound absorption at the ceiling was achieved. We showed that good acoustic quality can be achieved with only a minor reduction of cooling capacity.
