Annoyance response to aircraft noise exposure: a case study carried out in Brazil

Abstract

This study reports the first effort to assessment of community annoyance caused by aircraft noise exposure in Brazil. The purpose of this study is to assess the exposureeffect relationship for aircraft noise in Brasília. The percentages of people who felt annoyed and highly annoyed have been used to assess the dose-response and both were obtained using 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 relating to the aircraft noise annoyance was answered on an 11-point numerical scale. In total, 402 participants responded, with 51% female and 49% male. Logistic and polynomial approximations of the exposure-annoyance relationships for the year 2016 are presented for the DNL and L den noise metrics. The results show that for the same noise exposure, the aircraft noise annoyance in Brasília is higher 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.
