How much money per square ft would it cost if we wanted to ensure that little/no sound can be heard from upstairs. The basement is unfinished and we are also looking for cheap options.

There is nothing cheap about soundproofing.

To do it as you described, you would need safe n sound insulation in all joist cavities, followed by resilient channel on top of joists before drywall. On the resilient channel 2 sheets of 1/2 drywall with an acoustic seal.

Kyle, to do a proper job you'll need to add sound insulation (like Roxul safe and sound) in between the floor joists. Then add either drywall sheathing or a dropped ceiling. It isn't an inexpensive project but if you want the intended results, spend the money and do it properly.

Hey there, sound proofing is never really a cheap job if you want it done properly. The price can range depending on your expectations of sound proofing . The best way is to use acoustical rated insulation in all joist cavity's then a layer of 5/8 acoustically sealed then Rez bar with a layer of 1/2 drywall.

I was quoted $35-$37 per square foot by JAD Contracting, I suggest you stay away from them
