Replacing ridged duct with flex duct

The recording studio is in the basement of my home. I am building a RWAR.

I have 3 ducts that run from my house HVAC to other rooms in the house that run through the outer ceiling of the studio. They do not connect or penetrate the studio at all. My question is there any sound isolation improvement by replacing these (11' sections" of ridged HVAC duct with flex duct ?

I understand the air flow and HVAC concerns with flex duct. This is strictly from a volume perspective. Would replacing the ridged duct to flex duct help reduce sound transferring into the duct work through the ceiling ? Or is there no difference as it does not penetrate the studio ?

Thanks!
