The sound-absorbing cable feed arrangement can be applied in through passage in walls, ceilings, floors or similar, preferably combined with a so-called electric channel or groove, arranged along inner or outer walls or in intermediate walls separating rooms. The cable feed arrangement comprises a body (1), preferably elongated, in a material of good sound absorption properties, and which in a longitudinal direction has a number of holes (2), which are opened or filled, e.g. by the core (3) which is formed when the holes are made. In the open holes, cables can be inserted and the feed arrangement is tightly placed in a feed aperture in a wall, ceiling, floor or similar or tightly in an electric channel or groove provided sealed through a wall, ceiling, floor or similar. |
