If the ducts are metal, you can put them side-by-side because the metal provides shielding. But for non-metalic ducts, 6-inch edge-to-edge spacing is good, while 12 inches provides about as much noise reduction as you will get (for the 400-volt level).

FYI, That would be 150mm to 300mm.

Only the USA and Liberia are stuck in third world status when it comes to the SI system. [/pet peeve]
