The general objective of this project is to improve the sustainability of commercial ports by contributing to the reduction of noise pollution. It will build some infrastructure and invest in noise mitigation to carry out studies and assess their effectiveness, replicable in all ports of the cooperation area. This will make it possible to reduce heavy-duty road traffic generated by port activities and boat moorings, the main sources of disturbance induced by port sound sources, thus benefiting the neighbouring urban population. The project will implement actions after an initial acoustic climate survey and taking into consideration the grievances of the residents received by port management bodies and the public institutions in charge. In order to operate correctly and efficiently, RUMBLE will apply a monitoring strategy with the following features: 1) connected to the effectiveness of the mitigation works carried out with project funds in the pilot areas of Cagliari, Livorno and Ajaccio 2) aimed at evaluating the effectiveness of a large-scale project already carried out with its own funds in the Port of Genoa 3 ) defining the best actions to be implemented in the future in the Nice metropolitan area port. Focus groups and events will involve the target groups in all phases of the project, also to validate the results. These will include public bodies in charge of acoustic monitoring and planning, port companies and residents, also represented by Committees. The Network with the leaders of the other projects will ensure that the project can be repeated and transferred to other cross-border port facilities; the same will be carried out at European level through presentations by partners at institutional events and partner Universities before the international scientific community.
