Project Context and Objectives:The X-NOISE EV Coordination Action, through its network structure and comprehensive workplan involving experts groups, scientific workshops, international cooperation seminars and a common information system, addresses the noise challenges faced by Aviation. To this end, it will more specifically:- Evaluate EU-funded projects results and assess their contribution to the state-of-the-art.- Formulate, through development of common strategies and complementarity with national activities, priorities and key topics for future projects aimed at noise reduction at source, low noise operations, and improved understanding and modelling of the impact of aircraft noise in the community, including environmental interdependencies.- Ensure dissemination and exploitation of research findings, including technical information aimed at Regulatory Bodies and Policymaking Agencies.- Contribute to an improved integration of the European Aircraft Noise Research Community through a network of National Focal Points covering all countries with a technical interest in Aviation noise.- Identify potential reinforcement of future projects partnership through extended international networking and dedicated processes to foster new collaborations and promote novel ideas.Project Results:Definition of Research Agenda (Strategic Domain): Steps were taken to support the development of the new ACARE SRIA. Contribution was provided in view of the Volume 1 and Volume 2 documents, in a phased and comprehensive strategy aimed at achieving the noise targets set by the Flightpath 2050 vision.Technology roadmaps have been maintained and updated. Supporting the near term steps towards the 2035 target, a new technology roadmap for 2015 – 2025 is also being provided in line with the noise strategy for the novel architecture concepts. Annual Technology Status reports were produced.A Combined Roadmap for Balanced Approach and Impacts 2010-2025 has been developed. These research areas were also considered as excellent candidates for international cooperation.There was continued participation and contribution to the European modelling strategy discussion in the ECAC / ANCAT / MITG framework. In this framework a durable organisation structure has been developed to address Interdependencies Modelling.Two Noise Mapping seminar were organized to review the issues involved in the full mapping process. Research needs were identified for: model improvement, validation of model and database, supplemental noise metrics and land use planning. Case studies were reviewed. Based on the findings of the two noise mapping seminars a Catalogue of Good Practices was elaborated.An exploratory study undertaken to identify the causes for observed bad Land Use practices stressed the need for wider research in this area to advise main stakeholders accordingly. A workshop on General Aviation noise was held to support future identification of key issues andassociated research needs. A report was produced to summarize the identified research priorities. To complement this effort, a workshop was organized dedicated to Muffler designX-NOISE EV contributed to the OPTI progress assessment, using an approach similar to the previous AGAPE process to assess the current situation relative to the ACARE 2020 targets. The project also supported a presentation of the specific assessment methodology developed within the X-NOISE context at the occasion of the workshop on Evaluation Methodology organised by the EC. A new progress assessment was finally performed in 2015 for the benefit of ACARE WG3 to provide an update relative to the OPTI situation. In dealing with the further steps towards the -10dB target, the 2015 assessment exercise benefited from the achievements of the OPENAIR project as well as interim results from CLEAN SKY. In conclusion, relative to the ACARE noise target of -10dB per operation, the aircraft noise research effort can be considered as generally on track to meet its objective, but will require significant support in the few years remaining before 2020. Actions critical to the ultimate success of the comprehensive overall approach initiated around 2000 were summarized. A status of remaining efforts needed to draw was issued as part of the exploitation plan.The overall achievements to date and the proposed way forward (2020, 2035, 29050) were presented at the joint European Commission, ACARE and X-Noise event - Workshop on Future Trends in Aviation Noise Research held in Brussels in October 2014.In May 2015, a second workshop “Managing Aviation Noise Impacts - Mappping Future Research Priorities” was organised.
