QUIESST database of European NRD

QUIESST project

QUIESST - QUIetening the Environment for a Sustainable Surface Transport - is a project co-funded by the European Community's Seventh Framework Programme (FP7/2007-2013) that began on the 1st of November 2009. The QUIESST project addresses surface transport noise abatement (road and rail), considers cost benefit analysis and addresses the END objectives, covers true holistic noise abatement solutions through wave propagation and systems for passive compensation. Its team, made of 13 partners from 8 countries integrates the relevant stakeholders: Infrastructures, Industry, Universities, Research Institutes and SME. It addresses important environmental and economic concerns and will contribute to promote EU Noise Reducing Devices industry.

QUIESST database of European Noise Reducing Devices (NRD)

The database of European NRD has been developed in work package 4 of the QUIESST project. This database provides the different stakeholders with comprehensive data on the acoustic performance of European NRD and information on the practical use of those data. NRD manufacturers, laboratories and research centres as well as road and rail administrations will benefit from this information in the following ways:

  • The database gives an overview of past and currently available solutions for noise reducing devices and their acoustic performance according to the current European measurement methods for in-situ and laboratory sound absorption and sound insulation
  • It allows them to interpret, compare and relate the acoustic performance data generated by the different methods
  • It enables them to expertly use acoustic NRD performance specifications (e.g. for tenders)
  • It promotes the development of novel and improved NRDs
  • It allows them to assess the potential acoustic performance of new products in comparison to the existing market
  • It assists them in choosing the most suitable and cost-effective NRD type for their applications
