ACOUSTIC IMPACT OF CAPODICHINO AIRPORT BY THE USE OF THE AEDT SOFTWARE

About the study of the acoustic impact of the Capodichino airport (Naples), a new acoustic simulation soft ware was used to generate the study of noise propagation in the area near the airport and relative footprint. In the past, the INM (Integrated Noise Model) calculation code provided by the FAA (Federal Aviation Agency) has been represented the standard code for these simulation operations and widely used all over the international airports. Anyway, in the last three years, a new code has been implemented by the FAA, to overcome some of the lim itation of the INM. This new tool, named Aviation Environmental Design Tool (AEDT) present a new manage ment of the acoustic parameters (as, for instances the implementation of innovative sound absorption model such as the SAE-AIR-5534) and a different management of the acoustic maps definition (as, for instances, the use of dynamic grids) . It also allow to a contextual management of acoustic and air pollution (CO2) problems. AEDT also presents a catalog of aircraft updated and constantly updated, which INM did not have and for which equivalent aircraft should have been taken. In the framework of the present study, AEDT provisional results have been compared with data already available and based upon the use of the INM code. An in-depth study has been also dedicated to the comparison of numerical forecasted data and experimental one measured at specific target point through the use of the Capodichino Airport remote monitoring noise sys tem. The study has highlighted some of the peculiarities of the new software consolidating the opportunity to use AEDT as future planning tool for Capodichino and other airport’s scenario.
