Abstract

The invention concerns an intake air means (1), comprising an intake air chamber (2), a shell component (3) which is provided, in part at least, with holes (4) and which is connected to the intake air chamber, and an intake air connector (5) for introducing air in the intake air chamber. Air is distributed through the holes in said shell component into an indoor space (12). As taught by the invention, the shell component (3) is formed of comparatively light, and sound-deadening, material sheet, and the diameters of the holes (4) in the material sheet have a size not more than twice the thickness of the material sheet.
