Back to traps in ceiling, can a person have both, sound isolation and traps in the same cavity? Maybe a heavy layer of carpet underlay (www.soundown.com/carpet%20under.htm
) on the bottom of the floor wrapped down the sides the joists (all 1 piece per opening) then 2 layers of insulation, then screen/ mesh/ velvet, etc?
I'm thinking I'll try, it can't be worse than no insulation between the joists.
It wouldn't be over the entire ceiling, likely just around the edges where the wall meets the ceiling.
