CALM II
Advanced Noise Reduction Systems

Further efficient reduction of transport noise requires intensive research. CALM II aims at coordinating European research for advanced transport noise mitigation, in particular facilitating interdisciplinary networking and dissemination of knowledge, and at further development of the CALM strategic research plan. All transport modes are concerned: road, rail, waterborne and aeronautic together with outdoor equipements.

Background

Over the last 30 years, noise reduction has become an increasing priority for legislation and research, both at national and European level. Despite substantial improvements, today’s noise pollution is still a major concern of European citizens, with transportation as the main source of noise.

An estimated 80 million Europeans (ca. 20 % of the EU population) suffer from unacceptable noise levels. Estimations of the related annual financial damage lie between 0.2 and 2 % of the gross domestic product. This is an important societal problem. As mobility is a basic human need and an essential precondition for economic prosperity and growth in an enlarging EU, the adverse effects of noise must be reduced, while allowing a continued growth in freight and passenger transport.

Regulations limiting the noise emission from vehicles have been successful but not sufficient in the past. The Environmental Noise Directive 2002/49/EC (END) strives for avoiding, reducing or preventing harmful effects on human health. Therefore a major goal for future research is the transformation of END and the further development of noise policy covering the wide fields of noise assessment and abatement, new technologies and methodologies for improved noise control at source, and the future development of legislative standards.

The EC has published substantial noise reduction targets for the future, medium and short term, which can only be achieved by system approaches that involve research from all concerned areas. One general target is to find common research issues for road, rail, aeronautic and maritime transport utilising a maximum of synergies.

Objectives

The overall strategic objective is the synchronisation and encouragement of European transport noise research through a holistic system approach involving all related research areas. CALM II is designed to facilitate the networking of organisations, the coordination of activities and the exchange and dissemination of knowledge so as to optimise research efforts, reach critical mass, strengthen the complementarity and coherence of noise research objectives and enhance the impact at a European level.

Further aims are:

  • monitoring European research activities and identification of research synergies
  • identifying remaining research needs and setting research directions leading to updated noise research strategy plan
  • considering the situation in the new Member States and integrating the demands of national research initiatives
  • supporting the exploitation and dissemination of European noise research results
  • increasing public awareness of environmental noise and the awareness of noise research with young people (e.g. by involving promising young researchers with CALM II workshops).

Description of work

The whole work programme is split into five work packages (WP).

WP1 (Networking of European transport noise research activities) is designed for the monitoring of European noise research activities and noise abatement technologies at EU and national level across all relevant research areas of transportation noise, including outdoor equipment and generic issues like noise exposure, health and socio-economic aspects, city planning and infrastructure. The most important recent research activities are summarised in an inventory called the Blue Book. For identification of the remaining gaps and discussion of the needs for further research in an open dialogue, workshops are held with industry, research organisations and public authorities.

WP2 (Sectoral integration of different areas of transport noise research) improves the coordination and information exchange between different noise sectors and platforms with specific workshops together with the European technology platforms ACARE (aeronautics), ERRAC (rail), ERTRAC (road) and WATERBORNE (maritime).

WP3 (Noise research strategies) is designed for identifying technology gaps and research needs which is done in close co-operation with the European Noise Working Groups. This gives the input for the updating of the CALM Strategy Paper 2004, which is done twice within CALM II.

WP4 (Dissemination and exploitation of results) is focused on the information transfer and dissemination of results amongst all stakeholders, with a special focus on the new Member States and with specific workshops.

WP5 (Network management, coordination and administration) ensures an effective execution of the project including all administrative services like the organisation of meetings, reporting, etc.

Results

All results of CALM II are published on the project website. So far, the results comprise the reports of three workshops (one large workshop with RTD project coordinators for exchange of knowledge and results, and two specific workshops for identifying technology gaps and future research needs); the continuous updating of the CALM project database (with over 800 entries); the continuous maintenance of the homepage (now including a public calendar with major events on environmental noise in Europe) and the Blue Book, which is an inventory of 105 noise research projects and also contains a CD with all data in electronic format. An update (electronic, not printed) of the CALM Strategy Paper 2004 is under preparation and is to be published by the end of 2006. The update is focused on the latest information on the noise research road maps for air, rail and road traffic.
