AVALIAÇÃO DO AMBIENTE SONORO EM EDIFICIOS HISTÓRICOS:

ESTUDO SOBRE ESPAÇOS DE TRABALHO NO PAVILHÃO FIGUEIREDO VASCONCELOS DA FUNDAÇÃO OSWALDO CRUZ

Abstract

Noise causes effects that go beyond hearing loss. It does not have to be too loud to cause problems, especially where there is a high intellectual demand, need for concentration and oral communication. Providing a sound environment suitable for workspaces benefits not only the user satisfaction but also their professional performance. In the case of workspaces in historical buildings, acoustic adequacy taking into account new contemporary demands is of fundamental importance for the protection and preservation of cultural heritage. The aim of this article is to present the evaluation of the sound environment of workspaces in the Figueiredo Vasconcelos Pavilion of the Oswaldo Cruz Foundation (Fiocruz), located in the Historical Architectural Center of Manguinhos (NAHM) in the Northern Zone of Rio de Janeiro. The methodology was developed through a qualitative-quantitative study, which initially carried out an epidemiological investigation with the objective of identifying the uncomfortable sources of noise and the users' perceptions about the reality in which they are inserted. After analyzing the data extracted from the epidemiological survey, were identifyed the areas with high discomfort and technical visits, on-site observations and measurements of the sound pressure level were performed. The results were compared to the criteria levels established by ABNT NBR 10.152, providing reference data for future projects. Finally, this study concludes that is necessary to analyze the acoustic context of historical buildings, both the urban environment and the internal environment, in order to guarantee the quality of life to the user and the perpetuity of the built heritage.
