The element has two components (2, 3) resting on top of each other, and made of pressed fibrous plastic and pressed granulate plastic, respectively. One of the components includes an average fiber length of 2 mm to 35 mm and includes a large porosity than another component including a granulate size of 1 mm to 5 mm. The components include slots arranged on top of each other, where the slots are formed with same cross section at a transition region from the former component to the latter component. An independent claim is also included for a scrap tire for manufacturing a noise protection element.
