Tratamento acústico: prevenção a ruído de impacto em lajes e ruído aéreo em drywall para edificios multifamiliares

Abstract

Given the need to meet the growing demand for civil construction, coupled with the intense verticalization of buildings, the search for a place of tranquility, amid the constant noise pollution of urbanized society, grows every day. In this context, this study is focused on the presentation of materials and methods that can be used both in slabs and walls of residential buildings, aiming to present a comparison between insulating materials. For this, the characteristics of execution, budget and sound absorption capacity will be described and analyzed, and from this, the most advantageous materials will be presented. For the execution of this work, norms, articles, and some reference values in specialized companies' websites were used as a source of research, which will be referenced throughout the study. As a conclusion, the material that presented the best cost-benefit, among those analyzed, was glass wool, for its quality in sound absorption and its current cost.
