The Italian legislation regarding acoustic pollution is slowly going to be completed with the issue of all decrees in application of the framework law of 26th October no. 447/95. One of these decrees refers to the noise pollution produced by harbor infrastructures. There is little national and international information regarding this argument, above all because such infrastructures are highly complex, characterized by many acoustically different variables, represented by the single activities that are present in the infrastructure during the daily work. For this study seven Italian harbors were chosen, six marine and one lacustrine. For the choice of the harbors several criteria were used based on importance, territorial characteristic (e.g., characteristic of the harbor area, distance from inhabited areas), and presence of other activities (commercial, tourist and industrial). The first step of the work was the location of adequate cartography of the different noise sources present in the harbors and of the mainly exposed receivers. In a second time some measurements of noise were executed outside the harbor, in correspondence to the perimeter and at different distances along a determined directrix, and near the receivers mainly exposed. The results are presented in the present document.

In 1997 a decree was issued in Italy with the aim of defining the limits of noise sources inside discotheques and public show sites. ANPA (Italian Agency for Environmental Protection) has started research on about 30 sites in order to know the real levels of exposures to noise inside different types of public show sites and, after, carry out a first verification on proposed limits and methods, and also evaluate the possibility of using the automatic control systems stated by the rules. Such campaigns enable us to obtain elements that are very useful for the development of sectoral rules and for the planning of interventions.

The new Italian rules about noise pollution (General Law no. 447/95 and subsequent decrees) have caused the necessity of carrying out some measurement campaigns in order to observe the acoustic effects of various events and their interaction with territory and population. One of the research studies carried out by ANPA (Italian Agency for Environmental Protection) has dealt with a cognitive survey in motor racing sites and the noise impact that such infrastructures have on the surrounding environment. Measures have been done in and around motordromes, of which two are used for F1 races and one for motorcycles races; they differ from one another for territory orography, wind conditions and outskirts urbanization.
