AIRPORT SOUND IMPACT ASSESSMENT USING A GEOGRAPHIC INFORMATION SYSTEM 2008-36-0569
The airport noise is the origin of many adverse effects on the human's health and/or his well-being. The most frequent effects, noise annoyance and interference on sleep, have a few noise metrics associated to them. The DNL, LAD and LAN metrics are related to noise annoyance. Also there is, related to DNL metric, the percent of people highly annoyed. Interference on sleep is associated to SEL metric. So, the objective of this research is to develop the use of Geographic Information System (GIS) as a tool to help airport sound impact assessment through the evaluation of noise annoyance and the interference on sleep of the Brasilia's Airport.
