A noise-protection screen (1) provided with a number of sound-damping elements (2) and over the length of the noise-protection screen, spaced at a distance from each other with girders for the support of the elements, and a sound-damping element for a noise-protection screen. The noise-protection screen comprises an air cavity (8) delimited at one side by the sound-damping elements (2) and at the other side by panel-like elements (9). At the side of the sound-damping elements the air cavity is preferably in contact with the surroundings by means of air openings, preferably in the form of air gaps running longitudinally along the noise-protection screen. |
