FIELD: road protection devices.
SUBSTANCE: invention relates to a system of sound-absorbing protective fence for installation on the side or in the middle of the road. The protective fence system contains a set of support pillars, preferably vertically oriented, at least one noise-absorbing panel made with the possibility of mounting on the mentioned support pillars, and a set of longitudinal protective fences installed on the side of the protective fence system facing the road. The noise-absorbing panel contains noise-absorbing material that is placed in energy-absorbing material having holes. Energy-absorbing material is a mesh of expanded metal, containing the specified noise-absorbing material.
EFFECT: creation of a protective fence with noise reduction means that can withstand the impact of a vehicle colliding with a protective fence.
