Noise reduction with a diffractor
Reducing noise with a diffractor is an entirely new way of dealing with traffic noise pollution. This type of noise reduction has been incorporated into law since January 2020. Ahead of this the diffractor has also been added to the Geomilieu software package, as one of the most suitable measures for reducing noise alongside (rail)roads.
What is a diffractor?
4Silence originally developed noise reduction through diffraction back in 2012.
Diffraction is the scientific principle that sound waves can deflect when interacting with other sounds. A diffractor is an element with grooves of varying depths. Sound waves shoot into the grooves, where they start to resonate. Sound moves like water: it looks for the path of least resistance. So the troublesome sound waves above the diffractor deflect upwards, resulting in a quieter area alongside the road.
