Description du projet
Dévier le bruit du trafic pour protéger notre audition
Le trafic routier est l’une des sources les plus courantes de bruit environnemental, plus de 100 millions de personnes étant concernées par les niveaux nocifs de bruit dans l’Union européenne. Il est connu que l’exposition à long terme augmente le stress et perturbe le sommeil. Le projet WHISSPER, financé par l’UE, promouvra une nouvelle technologie développée par 4Silence, une entreprise établie aux Pays-Bas. Sa solution révolutionnaire, simple et durable est fondée sur le principe de la diffraction: dévier le bruit du trafic dans une direction ascendante pour réduire le bruit horizontal. Des tests menés aux Pays-Bas ont démontré que les prototypes sont très efficaces, faciles à mettre en œuvre et à entretenir. Le projet WHISSPER se concentrera sur l’optimisation de la solution 4Silence et la mise en place d’essais pour la tester dans des environnements opérationnels différents.
Objectif
The European expenditure on road and railway amounts ~€ 90 billion per year. Around 6% of the expenditure accounts for noise reduction measures, which equals to €5,43 billion. Despite spending these vast amounts of money, the overall exposure to traffic noise is escalating. Today, more than 1 in 4 Europeans is exposed to traffic noise levels dangerous to their health in their homes, schools and workplaces. The World Health Organization has classified traffic noise as the second worst environmental stressor affecting human health in Europe and the only one that is still growing.
Road and railway authorities recognize the problem, but budgets are limited, and currently available measures are based upon high cost solutions and have issues with life-time, noise reduction levels, and applicability. 4Silence helps to solve the problem. The technology company has invented a highly innovative, but also simple and sustainable solution based on the principle of diffraction, i.e. bending traffic noise in an upward direction in order to obtain horizontal noise reduction. It constitutes a revolutionary approach in the world of noise reduction, which traditionally focuses at noise absorption or blocking noise.
The prototypes are complete and qualified and have been tested in real world settings in the Netherlands. Demonstrations have provided evidence that the solution is highly effective in reducing noise exposure while having far lower cost (~50% cost reduction) and easier implementation and maintenance. This coincides with the increasing need of authorities for more cost-effective noise reduction measures. To ensure complete commercial scalability and enable international acceptance by road and railway authorities across Europe, the 4Silence solution requires optimization and scale up testing in different operational environments. With the support of several leading road and railway authorities, 4Silence aims to use the project set a new standard for traffic noise abatement.
