ANÁLISE DE PAISAGEM SONORA - PRAÇA OLÍMPIO CAMPOS, ARACAJU, BRASIL

Abstract

Soundscape, by Schafer in the 1960s, is understood as the relationship between the sound environment and the individual in their various forms of interaction. It is known that a sound experience can impact users in a positive or negative way. The main goal of this article is to characterize the soundscape of Olímpio Campos Square, located in central area of Aracaju, Sergipe, Brazil. The method adopted in this pilot study involved the following steps: characterization of the study site, collection of physical, traffic and acoustic data, application of questionnaires to analyze the users' sound perception; analysis and discussion of results. In the acoustic data acquisition step, sound pressure level measurements and audio recordings were carried out in the morning and afternoon periods at 13 points distributed throughout the square, totaling 26 data recordings. The results obtained in the acoustic measurements indicated higher values of sound levels in the border areas of the square, influenced by the noise of vehicular traffic, and lower values in their internal spaces. The most part of the sound levels in the boundary areas have exceeded the limits defined by NBR 10.151. The results of the questionnaires showed a greater predominance in the perception of sound events related to the vehicular traffic (automobile, motorcycle, truck and bus), sounds of nature (birds, movement of leaves on trees, wind and water) and different sounds (loudspeaker, music and voices).
