Avaliação do ruído interno e externo de uma obra de reforma: um estudo de caso

Abstract

This study explored the crucial relevance of noise control on construction sites for the preservation of workers’ health and the impact that noise has on the environment. The objective was to analyze the noise generated during a renovation project in a residential building, both within and outside the construction site. The methodology involved a detailed description of the impacts that a residential renovation project has on neighboring apartments. Specifically, the study focused on the noise generated by three commonly used equipment types in such projects. Rigorous noise measurements and data collection procedures were employed. Overall, the results regarding exposure levels and dose did not raise significant concerns, except for the case of the handheld circular saw, which exhibited a very high dose. Mitigation actions, such as sound reduction measures and limiting exposure time, were deemed necessary. Interestingly, the impacts outside the construction site were not worrisome. The study concluded that the use of personal protective equipment by workers was essential based on the conducted measurements. Regarding noise impacts in the vicinity of the construction site, further studies are needed. These future studies should include frequency analysis, a larger sample of construction projects, varying distances from the construction site, and extended monitoring periods. Such investigations would provide a better understanding of the impact on people’s health and the psychological aspects related to noise exposure in these contexts.
