Resumen
The sound sources propagated in the urban space, in particular the noise generated
by automotive vehicles, have raised the levels of noise pollution in big cities. For the
evaluation and control of the environmental noise, sound maps have appeared,
which allows to represent, through the isophonic curves, the sound pressure levels
active in the urban space. In this context, the present study aims to evaluate the
noise impact caused by traffic noise in the Castelo Branco neighborhood, in João
Pessoa / PB, through computational simulations in SoundPLAN® software. Three
different sound situations were analyzed: current scenario in the vacation period,
current scenario in the class period and hypothetical scenario of prediction for the
year 2026. Three different sound situations were analyzed: current scenario in the
vacation period, current scenario in the class period and hypothetical scenario of
prediction for the year 2026. As a result, it was observed that the neighborhood is
fragmented into two acoustic areas: the first one, with smoother noise levels, is
represented by the UFPB campus; The second one, with more intense sound levels,
it is the area of predominantly residential use. The resulting sound levels in the three
scenarios during the morning and vespertine periods are above the values
recommended by the legislation. There was little sound difference between the
current holiday and classroom settings. The urban morphology of the neighborhood,
especially the dense vegetation and the accentuated topographic differences, plays
an important role of sound attenuation. The urban noise critical points, in Castelo
Branco, reaching 83dB (A), are found on the edges of the BR 230 highway, in the
rotations and in the arterial ways.
