Análise do desempenho acústico da fachada de uma habitação do programa casa verde e amarela: estudo de caso na cidade de Guarapuava - PR

Abstract

Acoustic comfort is a topic that has been increasingly discussed in society. After the expansion of the population towards the cities, the generation of noise increased considerably, placing noise pollution as the third type of pollution that most affects the lives of human beings around the planet. Therefore, this work aimed to identify the acoustic insulation of the façade of a housing unit included in the Casa Verde e Amarela Program. For this, the guidelines of the engineering method present in the ABNT NBR ISO 16283-3:2021 were followed for carrying out field measurements. With the help ofmeasuring equipment and software for analyzing the collected data, it was possible to identify that the acoustic insulation of the façade was 27 dB, therefore it is in accordance with the requirements of the Brazilian performance standard ABNT NBR 15575-4:2021, satisfying the minimum conditions for noise class II. It was concluded then that the constructive system used for the vertical fences is satisfactory for the current noise class, with some suggestions for improvement, especially if there is a change in the noise class to class III.
