Wooden Noise Barriers
The absorbing barrier is particularly recommended whenever the installation of a sound barrier risks creating a “resonance box” or when the sound returned by the barrier causes further problems.
Absorbing barriers come in standard modules of 4.00m in length for a height of 1.00m.
These modules are stacked to obtain heights of 2.00 m, 3.00 m and 4.00 m.
The panels are covered in open latticework on the traffic side and positioned alternately at 45° right/left, and with a planed surface of planks arranged vertically on the resident side.
The panels slide into HEA-type galvanized steel posts, the size of which depends on the height of the panel and the “snow-wind region”.
Acoustic absorption DLalpha = 9 dBA
Insulation against aerial noises DLr = 31 dBA
All TERTU wooden screens have been tested according to standard EN 1793 by the Laboratoire Européen D’essais acoustiquede CSTB (CSTB European laboratory for acoustic testing), Marne la Vallée.
