    摘要: The present invention relates to a gas flow-through line with a sound absorption effect. Thereby the wall (5) of the line (1) has through-going perforations (2) having a diameter of less than 1 mm. The invention can for example find employment in the air suction hoses of a turbocharger of an internal combustion engine.

    摘要: There is provided a one-piece, removable load floor lining having sound insulation properties, for motor vehicles, having an upper shell (2) and a lower shell (1). The upper shell (2) is substantially flat and is hingeably connected with the lower shell (1) which is adapted to the contours of the trunk region, so that a complete unit is obtained which because of the double-wall principle achieves a large acoustic effect. The upper shell (2) further includes coverings (19, 20) which can be folded open by means of hinge means, whereby together with the contour-following configuration of the lower shell (1) there are provided closed hollow spaces (4, 5, 6, 7) of different depths, in particular as storage compartments for receiving accessory parts, baggage or the like, such as e.g. a so-called active noise control system.
