SUMMARY:

The last decades have witnessed an expansion of the urban network, an increase in population
density and in the vehicle fleet in urban centers, increasing the levels of noise pollution. This is
ranked second in the ranking as the greatest cause of diseases, second only to atmospheric
pollution, generating auditory and extra auditory problems. For the evaluation and
management of environmental noise, noise maps are tools to support decision making related
to planning and land-use planning. In this context, this dissertation aimed to map the road
traffic noise of the neighborhood Center, in the city of Aracaju-SE for analysis of the exposed
population. The work also presents an alternative methodology to specialize the demographic
data. Noise measurements were performed on roads with different morphologies, vehicular
flow data was collected and noise maps were elaborated by means of computer simulations in
the Cadna-A software. Demographic data were spatialized in the geoprocessing software QGis
to obtain the percentage of people exposed to high noise levels, according to NBR 10.151, and
formulation of conflict maps. The results showed that all measurement points contained levels
above the limit established by the standard, the least noisy was 61.2 dB (LAeq) at peak time (at
noon) and the noisiest was 74.6 dB in the morning period. The noise from light vehicles being
the main contributor to noise pollution. In addition, 57% of the population is in a region without
conflict with the standard, 26% are exposed to up to 5 dB beyond the acceptable limit 60 dB
(LAeq), 12% between 5 and 10 dB beyond the allowed and 4% receiving are above 10 dB. Thus,
along with the future interventions of the municipal Mobility Plan were indicated noise
mitigation measures, which should be implemented together for greater effectiveness and
guarantee the quality of life of the Aracajuana population.
