A partition (4) for separating the engine compartment (2) from the passenger compartment (3) of a motor vehicle comprises a wall (5) and a covering (6) of noise-insulating material on the engine compartment side of the wall. The partition (4) has convex or concave deformations (8, 9, 11) in one or several areas of the high noise occurrence.

A partition for separating an engine compartment subject to low-frequency and high-frequency noise and a passenger compartment of a motor vehicle, which partition comprises (i) a sheet metal wall located between the compartments so as to have one side adjacent the engine compartment and (ii) a covering of noise-insulating material on the side of the wall adjacent the engine compartment, the partition including at areas of high noise levels a convex deformation at an area of low-frequency noise and a concave deformation at an area of high-frequency noise, said wall and said covering being in spaced-apart relationship at said deformations.
