FIELD: road construction.
SUBSTANCE: invention relates to a noise-absorbing panel for use in a system of a sound-absorbing protective fence installed on the side or in the middle of a road. The protective fence system contains a set of support columns, at least one noise-absorbing panel made with the possibility of being mounted on the mentioned support columns, and a set of longitudinal protective fences mounted on a road-facing side of the protective fence system. The noise-absorbing panel contains noise-absorbing material that is placed in energy-absorbing material with holes. Energy-absorbing material is a mesh of expanded metal, accommodating the specified plate of noise-absorbing material.
EFFECT: creation of a protective fence with means for noise reduction that can resist impact of a vehicle colliding with the protective fence.
