The ports overlooking the Mediterranean Sea are often surrounded by densely populated urban areas affected by their noise. The overall long-term goal of REPORT is the mitigation of port noise emissions in the cross-border cooperation area to make the port infrastructure of Maritime Space more sustainable. A specific approach to correct noise management is needed. The different skills of the scientific bodies that make up the partnership make this a multidisciplinary methodology to be implemented and integrated within Directive 2002/49/EC, which does not specifically require port noise assessment but assimilates it to industrial noise without considering its characteristics and peculiarities, such as differing complex sound sources and their distribution and propagation. REPORT deals with this regulatory gap, which is common to all Maritime Space in a multidisciplinary way (technically, managerially and socio-economically), and suggests common methods for specific port noise management; as a result, its innovative approach is necessary to achieve the common and transnational dimension of European standards and directives. New algorithms and methodologies in the different sectors will outline and define the best common cross-border strategies that can be replicated for reducing noise pollution, making it possible to tackle the issue of port noise management in a comprehensive and therefore sustainable manner. Scientific and local public bodies will benefit from the project outcomes in terms of greater awareness of the problem and correctness and rigour of the methods to describe and deal with it successfully.
