isolating noise transmission in metal duct work
I'm about to install a drop ceiling in my basement and use the space as an audio recording studio. The weak link for noise reduction is the HVAC metal ductwork. While in the master bedroom on our 2nd story, I can clearly hear someone whispering from the basement. The only conduit for this quiet of noise source is the ductwork. Should I replace the metal ducts with fiberglass ductboard? Are there any effective "wraps" for this purpose? what are my cost effective solutions? Also, I would like to keep my ceiling as high as possible.
