Acoustic Treatment Help!

Okay. I found this

Concrete (unpainted, rough finish)	0.01	0.02	0.04	0.06	0.08	0.1
Concrete (sealed or painted)	0.01	0.01	0.02	0.02	0.02	0.02

Nice snag on the data and it does indicate some change between sealant and no sealant applied. I just don't know what the coefficient is all about...LoL. Like I said don't sweat things this soon because this echo'ey increase might be a advantage as compared to a disadvantage as you seem to be interpreting it to be at this point in time.

There carpet pads made to deaden sound. Make sure to buy one of those. Just Search the Net.

I assume we are talking about underlay as we call it in the UK. Should I be looking at foam then or rubber?

There are companies that specialize in sound deadening carpet pad (underlay). Search both names to get the most information. Not just just for audiophiles, there is a big market for that stuff. Plus with a concrete floor its good for comfort and and heat insulation. Buy the best you can afford.

Floating walls and ceiling in our basement media room, and deleting ducts (a major source of sound transmission) for a minisplit unit for that room. Pictures of the room are in my signature. Have not read everything, but attached a PDF of the info I gave our builder to create our media room. I used Kinetics Noise Control IsoMax clips and the builder and drywallers really liked them, construction was similar enough to standard that it did not slow them down much. The diagram was an overview; I worked closely with them and they also talked with Kinetics as needed.

The door is a heavy solid-core exterior door with full seals to reduce sound transmission.

I also added a file with the (very busy!) diagrams I made more recently to align speakers and such when I added overheads for Atmos. That also shows the absorption panels I added on the walls and ceiling. The floor uses conventional but thicker padding under the carpet.

HTH - Don
