Get yourself a larger size duct to fit around the other duct and then stuff with something in between (packing peanuts, old shirts (wrap around original duct first)) Also how are you holding your duct up? If you suspend it by some type of elastic it might help with reducing the vibrations that are being sent through your supports.
