Noise limits for aeronautical traffic near airport infrastructure refer to energy contributions of sound and flight distribution among runways essentially depends on weather conditions. Therefore, the acoustic impact of air traffic on the surrounding area can be predicted in real time as a function of the runways use thanks to dynamic control. The problem can be solved thanks to the development of a predictive calculation model (based on machine learning and, specifically, neural networks) implemented from historical data obtained from monitoring systems and correlated with the monitored acoustic parameters. This approach borrows from other sectors new possibilities for optimizing and managing airport traffic in order to contain the noise generated by aircraft in transit, a possibility that until a few years ago was unexplored in these terms. As a first approach, an IT tool has been created for the identification in real time of a configuration of the runways use that guarantees the maximum airport operation and noise levels within the regulations. In this preliminary phase, the number of variables analyzed and the historical database used for learning the neural network are limited and an approximation of less than 1.3 dB is established with respect to the data recorded at the noise control units. © 2021 Elsevier Ltd
