Frequently asked questions?
You can see an NoiseCare Fence at the nearest retailer which has an exhibition, you can see on the list of dealers which dealer has an exhibition.
As a private customer, you can NOT buy directly from Noisecare! We only sell to retailers who are set up in our dealer network, you want to be registered as a retailer of Noisecare, and we would like to hear from you.
No, we don’t have all the colors in stock, Galv. Ral 9005 Ral 7016
You have to expect 6-8 weeks.
80 cm = 8 screws
100 cm = 8 screws
They must always be ordered next door.
Our products are made of hot galvanized steel, PE mesh and stone wool.
You must contact the retailer that NoiseCare has been ordered through.
Yes, Noisecare is made of Steel, PE Netting and Rock Wool. These materials are in themselves maintenance-free. Therefore, all our products are maintenance-free.
We’ve created a video that shows you how to set up Noisecare.

DLα, NRD (note that if one needs to be completely correct, it is an “alpha” and not an “a”, since α (alpha) is normally the designation used for sound absorption)
This is a value that indicates how much the reflected part of traffic noise is attenuated when it hits the screen.
It is calculated by comparing the measured sound absorption coefficients at individual frequencies with the standard traffic noise spectrum at individual frequencies.
So, for example, if the screen has a DLα, NRD value of 20 dB and the screen is “hit” by a traffic noise level of 70 dB(A), the noise reflected back by the screen will be 50 dB(A).
This is the laboratory-measured sound insulation, which is the standard value measured for all building components (concrete walls, plaster walls, glass walls, windows, doors, etc.).
It is also the value we measure in the laboratory when testing noise screens.
ased on the measured value Rw, the DLR value is subsequently calculated by comparing the measured sound insulation at individual frequencies with the standard traffic noise spectrum at individual frequencies.
The DLR value thus indicates the sound insulation of the screen in relation to normal traffic noise. That is, it is the sound insulation (i.e., the attenuation of the noise from one side of the screen to the other) that the screen itself can provide. But the noise also moves over the screen and comes in from the side, so in reality, the difference in the noise level on the two sides of the screen is less than the DLR value. It depends on many things, including the height of the noise screen (the higher the screen, the better the attenuation).
Important: when in connection with data sheets and marketing, sound absorption in relation to DS/EN 1793-1 is specified, it is the DLα, NRD value that should be specified. And when specifying sound insulation in relation to DS/EN 1793-2, it is the DLR value that should be specified. One may also optionally mention the Rw value if desired.
