Abstract
A sound-absorbing panel comprising a padding layer comprising heat-bonded synthetic fibers is described. The sound-absorbing panel has a first outer face and a second outer face which are spaced from each other so as to form a panel thickness between them. The sound-absorbing panel also comprises a channel within the panel thickness. The padding material between at least one of the outer faces of the panel and the channel has a density greater than the density of the padding material far from the channel so that the panel is more rigid in the region of said channel.
Claims13
A sound-absorbing panel comprising a padding layer comprising heat-bonded synthetic fibers, the sound-absorbing panel comprising a first outer face and a second outer face spaced apart from each other so as to form a panel thickness between them, wherein said sound-absorbing panel further comprises a channel in said panel thickness and wherein the padding material between at least one of said outer faces of the panel and said channel has a density greater than the density of the padding material far from the channel.
A method of producing a sound-absorbing panel, comprising
- providing a padding layer comprising heat-bonded synthetic fibers, the padding layer comprising a first outer face and a second outer face,
- arranging a molding core between said outer faces,
- forming said padding layer with the molding core so as to form a longitudinal channel in the thickness of the panel between the two outer faces,
- wherein the forming step causes the padding material between at least one of said outer faces of the panel and said channel to have a density greater than the density of the padding material far from the channel.
