    Abstract:
    The methodological methods for a reduction of the noise pollution in the urban areas, mainly, can be advised in 8 operative points: 1) reduction of the source's noise; 2) control of the traffic; 3) planning of the urban and regional development; 4) building's shelter against the noise; 5) compensation's and incentivation's interventions for the exposed people; 6) controls activity and restaining of the noise's sources; 7) scientific research; 8) health education. For executive motivations we must, necessarily, divide the intervention turned to a reduction of the noise's emissions caused by fixed source compared to the noise's emissions determined by motor or railway traffic (mobile sources). This operative criteria have been utilized recently (1988) from Italian Department of Ecology for a bill. The controls of fixed source are made by Public Health Services of U.S.L. (Local Sanitary Unit) assisted, in case, by multiarea country's districts. The regulations of traffic can be took in consideration, in short time, only in more simple problems, as the setting up of pedestrian island or the suspensions of the heavy traffic, etc. The traffic's regulation must care same general data: the halved of traffic's flow in same rilevation's point, involve a reduction of only 3 dBA of the sound pressure level previously measured; if the percentage of heavy traffic is higher than 10% of the traffic's flow, the first intervention must be the no thorough fare to heavy lorries. In general, then, the best way for the resolution of vehicular noise pollution is the noisy emission's control of the single vehicle, because only the regulation of traffic's flow doesn't suffice to realise a enough reduction of noise pollution. For the resolution of more complex problems is necessary a preliminary stage to study and to plan those before to can carry out a typology of intervention. This necessity is, of course, more expensive in time and money; in fact, the solution of the problem can be the building of a efficient subway network completed by car parks in the terminal stations. In alternation at this draft, we can pointed out, also, same compromise resolutions like the appoint areas to limited traffic in the town or the break of continuity of the bus-line in the town. The compensation or the incentivation to make defence works against noise is a very expensive way and, moreover, they don't solve the problem for all exposed people in a future.(ABSTRACT TRUNCATED AT 400 WORDS)
