DECIBEL addresses the ports integrated in the insular cities of Bastia, Ile-Rousse, Olbia, Portoferraio and Giglio. It proposes a noise pollution reduction model specific to these insular urban ports too close to dwelling areas, often only ten meters away. It plans to come up with a set of pilot actions to apply said noise reduction model. It will monitor these actions to see which ones work better and determine good practices to ensure the durability and transferability of the results from the project. A study will probably be carried out in every partner port to come up with shared and specific noise pollution issues as well as an inventory of existing and effective noise reduction solutions. The totality of these elements will allow the drafting of a joint document integrating a common strategy and a cross-border action plan for the definition of land traffic regulation models for urban and people's activities to reduce sound transmissions. The plan will also address the problem of sound pollution coming from docking ships. Each partner port will carry out a pilot action consistent with the joint strategy and the cross-border action plan. Lastly, these actions will be monitored for their sound impact according to the cross-border action plan criteria. This evaluation will lead to the identification of good practices based on the results obtained. These will be listed in a common catalogue to contribute to the durability and transferability of the project results.
