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.
