Influência do ruído de tráfego em edificação na Av. Antônio Sales

Abstract

The development of urban centers took place more intensively in between the highways built in the 60s and 70s, generating an urban structure that grows side by side with the growth of road traffic. This problem has given rise to a recurring issue in the large Brazilian capitals, regarding the buildings on the edges of major avenues, which are subjected to levels of road noise incompatible with the tasks of rest and leisure. Thus, this study analyzes the exposure to traffic noise in a building on the margins of Avenida Antonio Sales, Fortaleza-CE. Through an exploratory research, measurements were made over 5 consecutive days, during daytime hours, between 7:00 am and 7:00 pm. It was verified that the equivalent noise levels measured, when measured with the windows and doors open, were close to the normed limit, and exceeded it in some occasions. However, when performing the same procedure with the windows closed, the limits were not exceeded in any measurement. In addition, it was possible to verify the performance of simulation algorithms for road noise, however, these were not representative when compared to the values measured inside the buildings. Therefore, it was possible to verify the importance of the acoustic performance of frames and the façade system as a whole.
