Abstract
The methodology used in several countries for airport noise simulations, including Brazil, is based on Day-Night Sound Pressure Level (DNL) metric. However, DNL metrics can in some cases bring distortions for sound levels, daily and nightly. The purpose of this study is to make an analysis of airport noise through the LAeq metric and propose new alternatives based on Day Equivalent Sound Level (LAeqD) and Night Equivalent Sound Level (LAeqN) noise metrics. We also apply the concept of acoustic influence areas for the analysis.
