Abstract
A sound shield is positioned between the burner chamber of a furnace and the portion of the furnace immediately in front of the burner chamber which is typically a removable door. The removable door has slotted vents that allow air to be drawn into the burner chamber. The sound shield is positioned between the slotted vents and the burner chamber in such a manner so as to prevent substantial amounts of burner noise being produced by burning fuel from escaping through the vents. This is done without unduly restricting the flow of air through the slotted vents to the burner chamber.
