Sistema de absorción acústico para muros a partir cascarilla de arroz, para disminuir la reflexión de sonido dentro de los espacios

Abstract

Within architecture there are acoustic phenomena that make it impossible to understand the word, these are presented by various factors. There are several materials that reduce these phenomena, of natural and synthetic origin. Some of the synthetic materials, have high costs for their production, both energetic and economic, in addition to requiring chemicals that can be harmful to the people who work in their manufacture, in its installation and final disposition. As a result, natural materials are comparatively more favourable, since they are easy to obtain since they are mostly agro-industrial waste, they are easy to process and also low cost (Proaños & Sandoval, 2010).Starting from the above, the rice husk is a natural fibre that can be used effectively to minimize acoustic phenomena in constructions. It is a waste that has various applications, such as concrete lightener, also for power generation. Because of this, we investigate the possibility of creating a material from this natural element that is capable of improving the acoustic conditions in the spaces. The present investigation is based on the following question: How to reduce the acoustic phenomena inside the spaces from panels whose base is rice husk and natural binder that is able to match and/or overcome the performance of existing materials, and at the same time be an economic and lasting alternative?
