摘要:
A bag for acoustic damping, where shredded material, preferably shredded flakes, is packed into the bag. The bag has a surface wall enabling a mechanical constrainment of the shredded material. The density of the packed shredded material inside the bag is in the range of 200-600 kg/m3. The bag is intended for use in a noise barrier for acoustic damping. The noise barrier comprises a front support element, a rear support element and a number of bags. The front support element and the rear support element are arranged at a suitable distance from each other, and the bags are stacked in at least one row in the vertical direction between the front support element and the rear support element.
