Av. Fab, is one of the main roads of the city of Macapá, capital of Amapá in Brazil. It is a route of approximately 3.3 km, where it has 05 public schools, 01 veterinary clinics with option of animal lodgings, a Justice Forum, a set of more than 5 medical clinics, several secretaries of state, State Legislative Assembly, Hospital Maternity Hospital, Bank of Milk, Hospital of Clinics, City Council, Macapá City Hall, seat of State Government and Church. The objective of this study is to show how this pathway is associated with high levels of noise pollution, which can seriously affect the population, especially hospital users and schools. For the work, 3 measurement points were chosen at Av. Fab, and were monitored at their peak times for one hour. A duly calibrated and certified decibelmeter was used. The measurements took place for two weeks, and on the first day, it was monitored point 01 from 07hs to 08hs, point 02 from 12hs to 13hs and point 03 from 18hs to 19hs. On the second day, point 01 was monitored from 6:00 p.m. to 7:00 p.m., point 02 was monitored from 7:00 a.m. to 8 p.m. and point 03 from 12 p.m. to 1 p.m. On the third day, point 01 was monitored from 12hs to 13hs, point 02 from 18hs to 19hs and point 03 from 07hs to 08hs. These measurements were repeated in the same sequence by the sixth day. Points 01D, 02D and 03D were determined for the parallel points to the right of Av. Fab and points 01E, 02E and 03E for the points to the left. Thus, the noise values were also measured. The results were compared and simulated 03 scenarios, the first one relieving the average noise by 30% and distributed to the parallel tracks, the second scenario reducing by 40% and also redistributing to the parallel tracks and reducing 60% of the noise and distributing to the parallel paths. The result shows the urgent need of the city of Macapá to develop its noise map and use it as an urban planning tool, avoiding future problems. It is clear that there is no planning that considers noise, even if it is a way, where there are the largest schools, the largest hospitals, the only motherhood in the capital, the entire secretarial center. The result is worrisome, as the local government intends to expand the bus routes along this route, being one of the biggest drivers of noise. For this work the Lden and DNL metrics were used.
