Análise do desempenho acústico de fachada executada em light steel frame: estudo de caso em uma residência na cidade de Guarapuava – PR

Abstract

Acoustic comfort has become an increasingly important requirement when evaluating a property, noise pollution is one of the biggest problems faced with the growth of cities and the increase in the number of cars. Thus, the facade of the building is of great importance in noise protection, making the study of its acoustic insulation increasingly relevant. Therefore, the present work aims to analyze the acoustic performance of the facade of a residence located in the city of Guarapuava-PR. Field measurements were carried out following the guidelines contained in the ABNT NBR ISO 3382-2:2017, ABNT NBR 10151:2019 and ABNT NBR 16283-3:2021 standards. Data regarding sound pressure level, reverberation time and background noise were collected and, with the help of measuring equipment and software, it was possible to analyze the results. Which showed that the facade is in accordance with the established in the Brazilian performance standard ABNT NBR 15575-4:2021, having an intermediate performance for noise class I. In summary, the constructive system used in the façade under analysis proved to be satisfactory for the region in question, and some changes can be made to optimize its performance, in case the class of the region changes according to urban growth.
