EVALUATION OF THE AIRCRAFT NOISE AROUND A REGIONAL AIRPORT BY COMPUTATIONAL METHODS AND EXPERIMENTAL VALIDATION

The study of the acoustic impact at the airport of Ancona-Falconara, a regional airport situated in central Italy near the Adriatic Sea, has been carried out in order to evaluate the acoustic influence of the airport activities in the surrounding areas. Through the use of a predictive model, several conditions on either air traffic or flights' different distribution among different directions of landing and take-off have been supposed. The evaluation of the noise produced by the airport infrastructure has been carried out using the evaluation level of the airport noise Lva, as it is defined in the Italian regulations. Moreover, the LAmax has been analysed for each type of aircraft both during take-off and landing in order to evaluate the maximum noise due to the traffic of every aircraft. Although this situation is very limited in time, it can create some problems to the people who live in the surrounding areas of the airport. Afterwards, phonometric recording has been carried out both with movable and fixed measurement stations in different points around the airport; such measurements have both had the purpose of checking the results given by the predictive model and the task of analysing the acoustic influence of every single air movement in order to define possible noise abating procedures afterwards.
