Have a look at the links for ideas. I have used the RSIC approach and it worked well. Note their site (see “RSIC assemblies by performance”) includes details for various combinations of material with the resulting sound transmission class (STC) ratings. Values of over 80 db sound difference can be achieved with concrete floors … although 60 db or so is more typical with a wood floor.

I have not used Green Glue, but it should work almost as well as RSIC’s and in some applications may be easier.

Have a look around the sites at the links and I expect you will find information you need to achieve what you need to tame the sound.

buy sound proof insulation from homedepot.they’ll teach u how to do it.
