Abstract
A muffler for an exhaust system of an internal combustion engine includes at least one muffler component with a perforation defined by a plurality of through-flow openings in a wall of the muffler component. The through-flow openings can be flowed through in a flow direction in the direction from an upstream side of the wall to a downstream side of the wall. At least in the case of some or all of the through-flow openings of the perforation, a through-flow opening flow cross section decreases in the flow direction in order to provide a through-flow opening flow-guiding surface.
