Metal Bent Curved Noise Barrier Arc Acoustic Panel
Curved/bent metal noise barrier with inward-bent top edge for superior noise diffraction. Aesthetic arc design, 15-25 dB(A) reduction for highways and elevated roads.
Bent (curved) metal noise barriers add an inward-curved top section that increases effective barrier height and improves noise diffraction. The arc shape provides both acoustic and aesthetic benefits, especially on elevated roads and expressways.
