A sound-damping ventilating device comprising an elongated block-shaped housing with a slotted ventilating channel terminating (8,27,27',27") at both ends in a mouth (9,10) forming a gap in a housing wall. The ventilating channel (8,27,27',27") and the mouths (9,10) extend substantially throughout the width of the housing, the slot walls of the ventilating channel (8,27,27',27") being partly bounded by sound-damping material and, at least in the vicinity of one mouth (9), by a wall (1a,2a,25,26,26a-d) of water-resistant material, whilst the other mouth (10) is covered by a valve element (11,28) with closable planar apertures. The ventilating channel (8,27,27',27"), over a part of its length, starting from one mouth (9) in the direction of the other mouth (10), extends slantingly upwards and may or may not be bent. The apertures are directed substantially perpendicularly to the direction of passage of the ventilating channel (8,27,27',27"). Standardization of parts with different heights and lengths is possible by adjusted dimensioning and design.
