Impacto do ruído ambiental em fachadas de edifícios verticais: altos na orla marítima de Maceió/AL

Abstract

As a consequence of the disorganized growth of cities, problems arise in vehicular traffic and conflict between the uses and occupations of buildings, a factor that increasingly intensifies urban noise. The neighborhood of Ponta Verde, with emphasis on Avenida Silvio Carlos Viana, has a large number of complaints registered by SEMURB (Municipal Secretariat for the Protection of the Environment and Urbanism). Most of these complaints are related to noise pollution, mainly due to the commercial establishments, bars and restaurants present in the immediate surroundings, as they are sources of constant noise. The objective of this study was to analyze the impact of environmental noise on the facades of vertical buildings on Avenida Silvio Carlos Viana in a routine scenario. The methodology applied is based on measurements of sound pressure levels, LAeq, performed on site on three days a week (Tuesday, Wednesday and Thursday). The data collected were applied to the CadnaA software for the simulation of sound maps and evaluation of the local acoustic scenario and the sound exposure that is found arriving at the vertical buildings by the sea, where the sound impact on the object of study was then discussed. Considering that in the daily scenario the sound data exceed the requirements of the current regulations, it is possible to verify that the residents are inserted in a sound environment with buildings exposed to high levels of residual noise, which can cause damage not only to hearing health, but also psychological and cardiac over time. The values found during the measurements exceed the requirements of NBR 10151 (ABNT, 2019), both in the value measured on the street, as well as the values that reach the facades, reaffirming the need and importance of urban planning to prevent urban sound pressure levels from being adequate so that good results can be obtained on an urban scale.
