4Silence
Reducing traffic noise, that is what 4Silence stands for. Sustainable noise reduction, innovative and sustainable solutions, scientifically underpinned and with proven results. Besides absorbing noise by means of quiet asphalt and blocking noise with a wall or screen, the whisstone of 4Silence is the latest worldwide innovation for deflecting noise. Several pilot projects at the Department of Public Works and various provinces now show that relevant noise reductions of more than three decibels can be realized with the whisstone.
Eric de Vries, director of 4Silence: "What makes it unique for us at this location is that we can just test along roads. We have space at our disposal here. We can test here and measure and drive past objects unhindered, but we can also actually show our products live here and we can experience them by driving past them. We are innovative, we are new, so we also want an innovative and inspiring place."
Eric on the location of Technology Base: "Twente is a very nice base of operations, because if I draw a circle around Twente, I grab the whole of the Netherlands, but also a very large part of Germany. So in that respect we are much more central in terms of area than in the west. If you draw a circle around the west, you have half a sea."
