Noise pollution is a disturbance to the environment that can bring a lot of inconvenience to the population, affecting their quality of life. Among these is the aircraft noise, which is generated by the engine and the aerodynamics of aircraft, especially during approach, landing, and takeoff procedures. The propagation distance of that environmental impact can be mapped by noise curves, serving for the preparation of a Noise Zoning Plan – NZP. This is a tool to aid the management of the use and occupation of land in the vicinity of airports. With the publication of RBAC No. 161, the current NZP from Manaus International Airport/ Eduardo Gomes – SBEG became obsolete. Based on data from operating the airport movement, noise curves of 85, 80, 75, 70, 65 dB (A) were generated by the INM software. While the two curves of noise in force, about to 75 and 65 dB (A), cover an area of 1249.49 hectares, with a population estimated of 20,959.58 inhabitants, and one school; the five noise curves generated in the INM cover an area and population 43.58% and 193%, respectively, higher, with four more schools. A city ordinance does not mention all the districts covered by the noise curves in force, leaving the most affected area without proper treatment. Therefore, we suggest the adequacy of municipal legislation to meet the requirements of RBAC No. 161.

Noise pollution is an environmental issue that can significantly impact the population’s quality of life. Aircraft noise, generated by engines and aerodynamics, can be mapped through noise curves and used for the development of a Noise Zoning Plan (NZP). With the publication of RBAC No. 161, the NZP of Manaus/Eduardo Gomes International Airport became obsolete. This study used operational airport data and the INM software to generate new noise curves at levels of 85, 80, 75, 70, and 65 dB(A). Compared to previous curves, the new ones cover a 43.58% larger area and a 193% larger population, including four additional schools. Municipal legislation does not cover all affected areas, suggesting the need for adjustments to comply with RBAC No. 161 requirements.
