Abstract

The long components (11) have a wall (16, 17, 23) extending upwards from a base, the side of which facing the noise source has sound-absorbing and damping properties. This side is concave with wall parts (17, 23) inclined downwards and inclined upwards, whereby at least the upwardly inclined wall parts (23) have sound-absorbing properties.
