ABSTRACT:
A sound damping element contains an inner wall and an outer wall, between which a cavity filled with absorption material is present, which are joined to one another. At longitudinal edges of the element, bent-away profile portions are disposed so that a junction with a similarly configured adjacent sound damping element can be made. The sound damping element is to be improved such that, with low production and material cost, a seal for preventing gas from passing through the element is achieved. Easy manipulation in assembly is possible, and the individual sound damping elements can be joined together without problems and, if necessary, separated from one another. At least one profile portion has a section such that at least a portion of a chamber is formed. At least in the portion of this chamber, a sealing element is disposed. Sealing is accomplished by this sealing element with respect to the adjacent second sound damping element.
