Minimizing Noise Transfer in Floor Joists

[Travis Boughton]

Hey guys and gals, I have my next short term rental property under contract. It is an up/down duplex, where we will be renting out the top and bottom unit through Airbnb/VRBO. My question is, does anyone have good info on how to minimize noise transfer between the two units. There is hardwood floors upstairs, which I am keeping (so no carpet comments). All of the work to suppress noise will be done through the basement by removing sheetrock and then doing whatever is necessary to eliminate noise. Any help or links to good info is appreciated!

Cheaper way,  install higher end rugs that will match decor  and color schemes.

It will help, not only on the floor noise but overall noise .

As a contractor, if you do the sound board in ceiling below then just install it over the sheet rock and install a new layer of sheet rock.  One more layer and save the demo and mess of same!

Lose 1/2 inch and need to buy longer screws and extend light fixture screws.

Simple!
