QUIESST - Quietening the environment for a sustainable surface transport
Overview
Background & policy context:
Noise Reducing Devices (like barriers, claddings, covers, and added devices following EN14388) play an important role in noise reduction: optimising their global performance is of major concern towards Sustainable Surface Transport.
Its team 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's (NRD) industry.
Objectives:
QUIESST merged, for the very first time and within a true holistic approach, true intrinsic product characteristics, whatever their materials and shapes, together with their extrinsic ones, in order to assess their actual global capacities to reduce the amount of people exposed to noise. It will address 5 main topics:
- NEAR / FAR FIELD RELATIONSHIP: linking the intrinsic characteristics to the corresponding extrinsic far field effect;
- IN-SITU MEASUREMENT METHODS: developing methods relevant of the actual intended use, allowing long-term performances control;
- COMPARING NRD's PERFORMANCES with different test methods: building a database comparing both existing and new tests results and providing the relevant relationship;
- OPTIMIZING NRD's GLOBAL PERFORMANCE through a HOLISTIC APPROACH: considering acoustic, non- acoustic and global impact optimisation, multicriteria optimisation strategies, and possible global performance indicators;
- SUSTAINABILITY: defining the relevant generic criteria and developing the first existing NRD's overall sustainability assessment method.
Methodology:
The final verifiable result would be the ACTUAL USE of the Guidebook to NRD optimisation as a reference tool for noise mitigation. QUIESST addressed the call as it concerned surface transport noise abatement(road AND rail), considered the cost benefit analysis and addressed the END objectives, covered true holistic noise abatement solutions through wave propagation and systems for passive compensation. Its team, made of 14 partners from 9 countries, integrated the relevant stakeholders: Infrastructures, Industry, Universities, Research Institutes and SME.
