Desempenho e eficiência acústica em construções considerando os aspectos socioambientais

Abstract

The research titled “Acoustic performance and efficiency in buildings considering socio-environmental aspects”, supervised by Silvio Motta, analyzes acoustic performance in buildings through the integration of technical criteria and socio-environmental responsibility. The study is based on the recognition that acoustic comfort is an increasingly pressing demand in modern cities, particularly in the face of rapid urbanization and the growing emphasis on quality of life. Given the rising levels of noise pollution in urban centers, the research evaluates materials and methods capable of delivering effective and environmentally sustainable acoustic solutions. The primary objective is to identify alternatives that combine strong technical performance with low socio-environmental impact. To this end, a qualitative and exploratory approach was adopted, grounded in a literature review of technical standards such as NBR 15575 and NBR 10152; recent scientific literature, including the theses of Marielly Anacleto (2020) and Klippel Filho (2017); and reports from entities such as ProAcústica and the World Health Organization (WHO). Five case studies involving the real-world application of eco-efficient materials were analyzed: recycled PET wool, cork panels, coconut fiber, concrete blocks with construction waste, and recycled EPS EcoBlocks. The results allowed for the assessment of the efficiency of these materials in comparison with conventional solutions. The study contributes to strengthening the dialogue between science, sustainability, and engineering by highlighting the role of acoustic performance in enhancing built environments, promoting healthier and more efficient spaces, and emphasizing the technical, environmental, and economic viability of innovative solutions in the construction sector.
