20240046909 · 2024-02-08 ·

Sound-absorbing material includes a monolithic main layer which is made of non-woven fiber fabric and has two opposite faces delimiting the thickness of the monolithic main layer. The monolithic main layer has a density gradient in the direction of its thickness. The monolithic main layer has a gradient in the fiber count in the direction of its thickness which decreases, passing from a first face to a second face of the monolithic main layer. The density gradient has an inverse trend with respect to the gradient in fiber count.
