Soundscape standardisation is an actual question of sound research, specifically in human and social sciences. Some late works have revealed that standardisation of urban soundscapes is or may be a consequence of contemporary space design, specifically when it comes to environmental or commercial design. In this perspective and in order to prevent this possible standardisation, but also to go beyond a negative and curative approach of "noise" and towards a more qualitative and crossed/interdisciplinary approach, the "DIAGPART" research took place. Its goal was double: \n1. Scientific goal: better understand how the multiple stakeholders of urban soundscapes (acousticians, urban designers, applied researchers in human and social sciences, soundmakers, local stakeholders) mobilise soundscape in their everyday activities; highlight the tools, methods, approaches, formalisations mobilized by the different stakeholders of urban soundscapes during a soundscape analysis; and understand if and in which ways they (could) mobilise other approaches and disciplines in their activity.\n2. Operational goal: propose a tool to help on setting up a cross-disciplinary analysis of urban soundscapes, addressed to the different stakeholders (designers, researchers, inhabitants, local stakeholders…). \nIn order to answer these questions, in addition to a recension of the ways in which the different stakeholders approach atmospheres and soundscapes, 6 workshops of discussion and in situ experimentation were carried out, based on the focus group methodology, followed by a transversal seminar . \nThe results of this research are both related to scientific knowledge about the ways and means that urban soundscape analysis is carried out by the soundscape stakeholders, and to a collection of operational tools that the stakeholders can use in order to approach urban soundscapes in a more interdisciplinary and global way.
