This project intended to carry through an acoustic mapping of the classrooms, laboratories and library pertaining to the State University of Maringá, as well as for the downtown of Maringá, Paraná State. The first stage will consisted of studying and presenting the parameters of interest to characterize a room or an environment as for its noise level, as well as the survey of the main points to be studied. The second stage included the in locu measurements of these parameters, according to ABNT and ISO norms and literature recommendations. Finally, collected data was statistically analyzed so that they could be compared to values stipulated by effective laws. After analyzing the collected data, it was possible to notice that the majority of the points were above the values allowed by law, especially those related to the city of Maringá; high noise levels were found in some sections. Regarding the State University of Maringá, the majority of points were above allowed levels, but in some cases they presented excellent quality. It is important to remember that the results obtained in the University are preliminary.
