Abstract :	[en] Noise barriers are popular devices to mitigate the impact of roads or railway noise on the community. So, heavy works have been devoted to improve their efficiency, both through their shapes and their building materials. In this work, the effect of ground scattering on the insertion loss created by a straight hard thin screen is investigated using a 1/10th scale model. The ground possesses thus a repetitive structure to induce scattering. Measurements are conducted on both sides of the screen and comparisons are drawn with a flat ground configuration.
