摘要：
The invention relates to a method for manufacturing a sound-absorbing element by stacking on top of each other a plurality of discarded vehicle tyres (2) and at least partially filling the space (12) formed by the thus stacked tyres with a filler (15). A curing material, for instance a foam, is herein chosen as filler, whereby the tyres are mutually connected.
The part of the space not filled with foam can further be filled with a weighting material (16), for instance waste material reduced in size. A robust sound-absorbing element is thus formed in rapid and simple manner and at low cost.
The invention further relates to a thus formed sound-absorbing element.
Finally, the invention further relates to a method for manufacturing a noise barrier by placing a plurality of such sound-absorbing elements mutually adjacently on a ground, in addition to a thus formed noise barrier.
