Resumo: Environmental noise in urban areas is known to cause functional abnormalities reflected in human health and behavior. In developing countries such as Brazil, public schools are exposed to high levels of noise due in part to poor infrastructure, especially with regard to noise attenuation. In schools exposed to noise levels above the limits specified by regulations and international guidelines, students and teachers are at greater risk of health problems, and performance may be compromised. In this study we evaluated the impact of environmental noise on children and teachers at three public schools (a kindergarten, an elementary school, and a high school) in a Northeast Brazilian metropolis, with emphasis on noise generated by street, above ground rail and air traffic. Environmental noise maps were generated and teachers were administered questionnaires focusing on the impact of noise pollution on health and performance. The study was intended to subsidize efforts at urban planning and public policy making by measuring actual noise levels and probing their possible effects. As shown by our results, public schools are in urgent need of noise attenuation measures, and enforcement of noise emission regulations for public transportation needs to be more emphatic.

Dans les pays en développement tels que le Brésil, les écoles publiques sont exposées à des niveaux de bruit élevés à cause des mauvaises infrastructures, en particulier dans le domaine de la protection contre le bruit. Dans les écoles exposées à des niveaux de bruit au-dessus des limites fixées par les normes et directives internationales, les étudiants et les enseignants sont à risque plus élevé de problèmes de santé et leur performance peut être compromise. Dans la présente recherche, nous avons évalué l'impact du bruit environnemental sur les enfants et les enseignants de trois écoles publiques (une école maternelle, une école primaire et une école secondaire) d’une métropole du nord-est du Brésil, en mettant l’accent sur le bruit généré par le transport routier, le métro et le transport aérien qui sont d’importants générateurs de bruits dans les centres urbains. Des cartes de bruit environnemental ont été générées et les enseignants ont reçu des questionnaires centrés sur l'impact de la pollution sonore sur la santé et les résultats des élèves. Cette recherche visait à soutenir les efforts de la planification urbaine et de politique publique, à travers une mesure réel des niveaux de bruit et de leurs effets possibles. Les résultats démontrent la nécessité d'adopter des mesures de traitement acoustique dans les milieux scolaires et d’appliquer plus fermement les réglementations à propos des émissions sonores dans les transports publics.Canadian Acoustics2019-09-23T12:53:43Z2019-09-23T12:53:43Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfARY JUNIOR, I.
