The Fortaleza noise mapping project—a tool for the definition of noise action plans for the airport located in the center of the municipality

Abstract

Studies of the impact of noise from Fortaleza International Airport, located well within the urban area, based on the noise mapping project that was created for the spatial representation of indicators of ambient noise in the city of Fortaleza, Brazil, which provided a tool essential to analyze and define strategies for the control of noise pollution in the city. This is the first noise map drawn to scale in a large city in Brazil. Noise emissions from major sources that contribute to the sound environment of the city, including road traffic, railway noise, aircraft noise, industrial noise, noise and entertainment areas were included. The method followed a hybrid approach, essentially calculating complemented with experimental measurements for validation and calibration. The study of airport noise allowed detailed results for equip lawsuit against the noise produced during operation of the airport.
