Analysis of the effects of aircraft noise in residential areas surrounding the Brasilia International Airport [paper in Portuguese]

This study aimed to analyze the perception of discomfort caused by aircraft noise in residential areas surrounding the Brasilia International Airport (SBBR). The study was divided into two parts. At first, noise measurements were conducted in four residentials zones and the sound pressure level determined by the parameters: Leq, Lmax, Lmin, RF, SEL and IPR. In the second part, we applied a questionnaire adapted from the project Eurocontrol (European Organisation for the Safety of Air Navigation). The results of field measurements indicate regions with soundscape compromised and with potential of nuisance, especially at night. Was obtained, from analysis of questionnaires, that the respondents female sex if showed more sensitive by the noise of cars and planes and realize more intensity the noise from road and air traffic. It was found dissatisfaction with the interference caused by the noise of aircraft in daily activities and indicated as reactions noise-related: headaches, sleep disorders, stress and difficulty concentrating. It is noteworthy, that in the region with lower noise, the respondents are more sensitive to the noise of airplanes and the values of acoustic parameters measured would justify the negative reactions of respondents to the air transportation noise. Moreover, there was a direct relationship between the perception of annoyance and discomfort with the sound pressure levels measured.
