Not sure about reducing the noice, but they are heating DUCTS, not DUCKS. If you have Ducks, that may be the problem. Quack!

A couple questions to you is as follows:
Is the blower running continious or only during the heating cycle?
Do you hear the noise when the blower is off and the ducts are starting to cool down?
My first thought is to have someone check the blower wheel for an in-balance. Just as car tires, these have small weights installed from the factory to keep them in balance. Possibly the motor shaft bearings are bad and causing this vibration which will resonate right thru the ductwork.
If you have a professional look at this, see if they can install what is known in the trade as a flex collar off the plenum. It is nothing more than a canvas connector joint between the furnace and ductwork and does not transmit any vibration.
Another quick thought could be the possibility of your unit being starved of return air or 28 gauge or thinner metal utilized for the main trunk line and or not being cross broke to add rigidity.
See if you can isolate the sound when it happens....it can not be everywhere, and post what you find.

Most likely, you have sheet metal ducts that are expanding from the heat. This causes them to change shape and move relative to the struts that hold them. Both movements generate noise that echoes along the ducts and into the house. Unless you're prepared to go to a more heat resistant but much more expensive solution like fiberglass or plastic, you're going to have this kind of movement. The most common solutions are to wrap the ducts with additional insulation (which will also dampen noise & vibration) or to replace as many sections as possible with flexible, non-metal ductwork, which will dimish movement and echoing.

Never heard of ducts making noise, but you may want to have them cleaned. Maybe they're shaking, so try anchoring them to a joist or something.

ask the Guy's at Home Depot or some Guy's what sell furnaces because yes there is something you can do. It is sometimes the plenum what is rattling, so there is some tape you can put over. Just go and ask there is more you can do.
