Uso do bambu laminado colado (blc) para condicionamento acústico

Abstract

This paper aims to make a proposal, at the preliminary study level, of a panel in Glued laminated bamboo (GlumBam) + coconut fiber for acoustic conditioning of indoor architectural spaces. The purpose of the project is to develop a model with a design that allows various forms of use and is able to reduce reverberations and noise in environments that require acoustic treatment. Recent studies show that besides its eco-efficient and sustainable character, bamboo presents itself as a more resistant material than conventional woods (such as oak and pine), besides being extremely light and attractive. It is noteworthy that, from the literature review, it was possible to identify the potential of bamboo as an absorbent material. However, given the importance of a product with good noise absorption, the incorporation of coconut fiber is proposed because it is a material with great potential for this purpose. To exemplify an application of the proposed GlumBam panel, the paper presents a simulation of a "cloud" type acoustic lining system to be installed in the auditorium of the Technology Center of the Federal University of Paraíba, where there is no acoustic conditioning appropriate to the activities developed there. The work is concluded with the execution of a prototype of the proposed GlumBam panel, for future performance analysis by the research group of which the author is part.
