Elaboração de painéis acústicos com a utilização de materiais sustentáveis alternativos

Abstract

There are a multitude of raw materials in nature that have not yet fully exploited their potential and that can present solutions for several current needs and become very useful in the elaboration of products of the most varied. Since the issue of sustainability is one of the great demands of today, it is essential to develop research to enhance these raw materials in the development of projects that present this differential. The objective of this work is to elaborate acoustic panels exploring alternative sustainable materials, such as: vegetable loofah, cob and corn straw, with a view to creating an innovative and sustainable product. To carry out this project, an exploratory methodology was used, based on the authors Baxter and Bonsiepe, with the application of Design Thinking tools and an emphasis on the areas of acoustics, sustainability and design. Research has been done on the possible applicability of vegetable loofah and corn as a sustainable and economical alternative in the acoustic treatment of environments. To this end, there was a design investigation to identify the product concept, determine the target audience, select the materials and generate alternatives. For the prototyping, tests were carried out with the application of vertical and horizontal cuts on the vegetable plugs and on the ears and corn straws and collages on structures made with reused slats and Eucatex agglomerate, where different thicknesses were tested and panels with varied perforations were used, having different perforations. as a result, the elaboration of 6 panels with sustainability characteristics, which can be used in the design of environments and which have possible applications to mitigate the reverberation of the spaces where they are inserted.
