Abstract

A device for reducing body noise emission from sheeted units, especially exhaust gas tubes (5) and housings in motor vehicle combustion engines comprises attaching (3) an additional element (2) at a point of maximum oscillation amplitude to give friction with the sheet. This element is thin-walled and covers a minimal part of the sheet surface.
