• Abstract:

  This study reports the first effort to assess community annoyance caused by exposure to aircraft noise in Brazil. The aim of this study is to evaluate the exposure-effect relationship for aircraft noise in Brasília. The percentages of people who felt irritated and highly irritated were used to assess the dose-response, and both were obtained through a survey. The survey was sent by e-mail and was carried out among residents in the vicinity of Brasília International Airport. The questionnaire contained questions about: personal data, noise annoyance and interference with daily activities. The question concerning annoyance with aircraft noise was answered on an 11-point numerical scale. In total, 402 participants responded, being 51% female and 49% male. Logistic and polynomial approximations of exposure-annoyance relationships for the year 2016 are presented for the DNL and Lden noise metrics. The results show that for the same noise exposure, the annoyance with aircraft noise in Brasília is greater than those reported in the European Community. Finally, the dose-response models developed in this study contribute to a better understanding of the impact of aircraft noise in populated areas around airports in Brazil.
