An array of various ceiling isolation options and their relative performance.

If you want a lot of isolation, the #1 thing to do is decouple the ceiling drywall from the joists. That alone will put you in a higher isolation category.

Don't spend a lot of time and money looking at insulation. Simple R19 fiberglass is excellent. Cheap and about as good as it gets

Stick to massive standard 5/8" drywall at $8 a sheet. Excellent source of mass
