What we hear is the blower. In most installations there's a direct line of sight to the blower on the furnace, that's what you hear. If you can "break" that line of sight without choking off air flow you will greatly reduce the sound, sound travels in a straight line and doesn't "bend". On residential furnaces I've used fiberglass ductboard to redirect the air, place the board so the fiberglass faces the blower which helps absorb the sound. Sometimes there's enough distance behind the return grille to suspend a piece of ductboard, directing the air around the edges and blocking line of sight.
