Dear visitor, you've reached silentroads.nl, a website for the dissemination of knowledge about road traffic noise reduction. We thank you for your visit to this site.

We believe that a significant road traffic noise reduction can only be achieved by tackling sound at the source and that by doing so the general quality of the environment, both in cities and in the country-side, will be improved, without spending money on expensive noise barriers.

We are aware that source reduction of road traffic noise is not an easy task. The process of sound generation and propagation is very complicated, the manufactures of the vehicles, the tyres and the road surfaces operate from very different backgrounds and solutions have to meet requirements on costs, maintenance, energy consumption and safety.

Working for more than 10 years in the field of source reduction of traffic noise teaches us that real steps forward can only be made when 1) basic knowledge, 2) high quality measuring standards, 3) structured measurement data for various products, and 4) effective policy are integrated into a balanced strategy that we call the silentroads approach. The buttons in the upper right corner will give you easy access to the silentroads subjects.

Our work in these topics has produced results that we find interesting and we enjoy the possibility to share this know-how with you as a contribution to silentroads. We welcome you to explore this site and find information that you can take home. Possibly, you also would like to share information with the silentroads community. If you send an e-mail to us with your experience, suggestions etc., we'll be glad to put it on the site and the community will be grateful for that.
