Nope, nothing on the slab other than carpet pad/carpet. I was planning to do Serenity Mat, but Soundproofing Company said that for my room, there would be zero benefit. I even proposed getting it anyway, just in case....and they said “Suit yourself, but we have decades of experience and we are telling you that it will not benefit your room. Now, they had drawings of the room, as well as the rest of the basement, and they knew the measures I was taking to soundproof (15 buckets of green glue and at least 20 tubes! Ugh!). They also told me that Whisper Clips would offer no benefit over the IB-1 clips in my situation (I again fought them on this, since everyone else was using whisper clips), and they again said “suit yourself, but we know our stuff and there will be no benefit. Now, why there was no benefit to my room? It could have been the location of the room in the house, or it could have been the Soundproofing design obviates floor treatment...whatever the case, I listened to them, and I’m glad I did. Can’t hear a peep in adjacent rooms beyond 1-2 feet of the theater airlock (communicating doors). In the room on the other side of the screen wall, separated by two stud walls and a total of six drywall layers+green glue, it’s pure silence.
For other rooms, Soundproofing company has recommended both whisper clips and serenity mat, so my guess is this: there are room/house variables that only professionals can analyze to determine the need for those specialized items. I’m glad I did not need the Serenity mat, as I was starting with 8’ ceilings before soundproofing, and the total soundproofing snipped about 3 1/2” off the ceiling.
