Abstract (en)
[origin: WO03078740A1] The invention relates to a noise abatement wall. The device comprises an approximately planar base and elements (1) which are raised and/or hollow, each comprising at least one recess (2). A configuration with a fractal zone ranging from 1cm to 50 cms is revealed by said base and raised and/or hollow elements (1), the fractal dimension thereof being greater than 2.5, enabling the location of waves in the sound frequency range in the vicinity of said elements (1).
