QUIESST Database on intrinsic acoustic performances of European NRDs

The European Noise Reducing Devices market offers many already approved products, while many new ones are appearing. However, even if the European product standard EN 14388 [1] is published since 2005, no comprehensive database of the NRD acoustic performances does exist yet. In the frame of the European project QUIESST (2009-2012), Work Package 4 deals with the performance evaluation of Noise Reducing Devices investigating the relationship between laboratory and in-situ methods. Having the clear scope to help manufacturers, infrastructure administrations, research centers and engineers to have more detailed information on the correlation between those methods and to win a better overview of the different products present on the market main objective of this work package was the creation of a comprehensive database for the noise barriers present currently in Europe. The Database provides the different stakeholders with data on the acoustic performance of European NRD and with information on the practical use of those data. The paper summarizes the main findings of work package 4, describing the use of the database developed within the QUIESST project.
