In the frame on the European directive 2002/49 for the study of the environmental noise, Greece, between 2012 and 2016, had the opportunity to develop a specific methodology in order to analyse the sound environments of several neighborhoods in large and medium size cities of the country : Volos, Larissa, Heraklion, Chania, Agrinio, Corfou and Thessaloniki. This paper presents the multidisciplinary approach used and shows how noise data are cross analysed with urban and architectural data and perception descriptors by inhabitants. It shows how theses results has been implemented in the several noise actions plans proposed to the authorities. Finally, the paper discusses the necessary evolution of this approach, not only to reduce noise exposure problems, but above all, in order to make the city evolve towards the production of sustainable sound environments.
