LIMA, Aline Maria Meiguins de2025-03-172015https://rigalileo.itegam.org.br/handle/123456789/743Noise pollution in Brazil, a country with many metropolitan areas with population amounts around one million inhabitants, it is still not subject to effective preventive action by Brazilian municipalities. The major cause of noise in sensitive areas is the lack of urban planning in cities. Obviously the traffic noise, airports, and the activities cluster in one place will affect all its surroundings, making the region inappropriate for certain purposes: residential, parks, hospitals, schools, kindergartens, etc. In many cases, public roads with lower sizing to incoming traffic border sensitive areas and affect the environmental quality. According to WHO (World Health Organization) the problem is recurrent in developed and developing countries, becoming worse in the last ones due to the rapid and unplanned growth of cities. How to act when the noise pollution is already present in the city and the uses of spaces have lost environmental quality? The European Union realizing the seriousness of the problem decided in the European Parliament that all member countries should make noise maps of cities with a population of over two hundred fifty thousand inhabitants. The preparation of noise maps allows analysis of the sources, trajectory and influence of the emissions and the definition of corrective and preventive actions. The elaboration of such maps is not usual in Brazilian cities. We present a noise map of a region of Manaus and we introduce a proposal to build such a tool to be used throughout the entire city. The results shown on the map represent an unknown reality and can guide corrective actions.ruídomapa de ruídomapa acústicopoluição sonoraplanejamento urbanopdf.Engenharias; Engenharia Civil; Meio Ambiente e Recursos Naturais
