I'm in the process of finishing a room in the basement that is directly under the master. It will be used as a media room, and temporary bedroom for my husband when we have a second baby at some point in the future, so I'm concerned about sound going up but more so with it traveling down when I'm waking up and walking around with a crying baby (baby will sleep in our room for the first year).
The ceiling is totally open right now but has two heating ducts running through it. Is it necessary to soundproof all spaces between the joists? We're looking a rock wool or regular fiberglass insulation with a sound barrier. We're also considering skipping soundproofing entirely if the difference will be negligible. The master is carpeted with a decent pad, installed within the last year. Does anybody have experience with this or advice?

In our last house we used Roxul between the joists in the ceiling. It did help *some* with noise transmission, but because you have those metal returns & ducts in the ceiling you're not going to get the full sound reduction you're looking for. You could reduce it a bit further by looking for a sound reducing product that goes between the joists & the drywall. One I've seen mentioned is 'green glue' it stays flexible and acts as a slight barrier which can reduce the transmission of noise. I've also seen a system installed on Income Property that was like a flange or something that did the same thing (can't find info on that now though).
So yeah, it will help SOME but because of the ducts & returns it won't be great.

We live in a four-flat in Chicago and recently soundproofed our master bedroom. They did floating clips from the joists and then it was double layers of sheetrock with sound proof glue between and regular insulation. We can still hear walking (our neighbors are heel walkers and stomp) but no audible noise which was a big issue before. We could hear everything.

I've seen those clips before. I also know someone who put up sheetrock on the ceiling and then also wood tongue and groove in a basement to soundproof. I think it worked well for them.
I also wonder if you could do something like these on the ceiling after you finish?
Sorry, no real answers, just that we're looking for ideas and have been talking to friends recently for something similar when moving our kids to the basement under our room.
