EVALUATION OF THE NOISE POLLUTION AROUND THE ITALIAN AIRPORTS

This paper describes the work of the research group IAA (Acoustic Airport Pollution). In the last years the group has studied the aircraft noise problems through contracts with Institutional Corporate Office (Ministry of the Environment) and Private Office (ISPESL Institute to prevention and safety on the job). The actual noise descriptors proposed by the Italian and European standard and the real correlation with the human response to aircraft noise are examined. The development of a filing and management system of the environmental measurement is proposed. In this paper the procedures used for characterizing the aircraft noise in a zone neighbouring the airport are illustrated. It’s been able to verify that aircraft noise is characterized by the presence of frequencies that influence the receptivity of the human ear. The presence of this frequency has allowed us to affirm that the aircraft noise descriptors must depend from a factor that represents the frequency analysis in the over fly. Therefore it’s studied the potentialities of the system of data handling produced by the research group. Through the various phases of filing and management of the dates this important tool of analysis allows checking fast and satisfactory environmental situations in the Italian airports. The flexibility of this tool will allow the environment future data management in according to various European directives.
