NEW AIRPORT NOISE MANAGEMENT TECHNIQUES

The Lombardy airport system is composed by the three international nodes of Malpensa, Linate (respectively the second and the third Italian stopovers) and Orio al Serio (third Italian freight node). They involve almost the 23 % of the totality of the Italian airport departures and approaches. Montichiari airport is included as well: less important than the others, it is assuming a growing strategic role. Thus, airport noise pollution is one of the main issues in the Lombardy environment care framework. It has led to the realization of three noise continuous-monitoring systems in correspondence of the three main airport nodes. In order to face the existing population demand of noise control, the Regional Environmental Protection Agency (ARPA) together with the Lombardy Regional Administration, has set up a specialized technical centre (PTA – Presidio Tecnico Aeroportuale). The main activities and aims are: 1. Monitoring system checking; 2. Elaboration of airport noise impact scenarios
