I previously have a thread about how I should construct my floor. We have added an extra floor, and the old attic floor joists now serve as the floor. I want to build good impact sound insulation within reasonable limits. However, it's not about separate apartments. We have all the bedrooms on the upper floor. It would have been worse if it were the other way around.
Given conditions: I have 220 floor joists with a spacing of 60 cm. On these, I have screwed 22mm chipboard. This setup is finished, so it's the starting condition. I will have underfloor heating and parquet on this.
In my previous thread, I planned to lay a 20mm Paroc impact sound board, followed by slotted 22mm chipboard, and then 14mm parquet. I am beginning to realize that the building height becomes a bit problematic, especially at the stairs.
So, I have rethought. I still plan to start with a layer of grooved chipboard (22mm) over the mounted 22mm chipboard. My consideration is to get a soundproofing mat like ACOUSTIC SILENCE 700, 2mm instead. Of course, not the same as the Paroc board, but maybe better than laying chipboard against chipboard.
The question is, how does such a construction hold up, do you think, for those of you with some building experience? From below: 220mm insulated with old sawdust or Isover where we have removed the sawdust - 22mm chipboard screwed on the studs - impact sound mat - grooved chipboard - felt paper - parquet. Since we have removed the old board floor, this will increase the height over the stairs by about 38mm. Then we will install renovation steps in the stairs which will offset some of that.
I have also considered replacing the underfloor heating chipboard with EPS, but concluded that the smallest ones with 16 pipes build up to 30mm. Also, EPS can create a drum sound and is not particularly sound insulating. Is that correctly thought?

Built several apartments, we've used acoustic profiles in the ceiling with double gypsum on that, the joists are 220 with insulation, chipboard, 50mm impact sound insulation, double floor gypsum, foam, and parquet. Walking in socks, you couldn't hear anything, but with shoes, the impact sound could be heard.
With your planned construction, I think you should expect some noise. I don't really know what you can do when you can't build any higher... Can you have acoustic profiles in the ceiling below?

Time to revive my old thread about footstep soundproofing. It's quickly approaching completion, so I thought I'd do one final round for some feedback. As mentioned, I've wanted to do some footstep soundproofing and create a somewhat damped space between the floors in our house. We're not talking about apartment separation here. Impact on the ceiling below is also not currently an option.
Prerequisites:
I've screwed 22mm particleboard onto a fully insulated 22mm floor joist. On this, I'll lay 22mm grooved particleboard, and complement it with a soundproofing mat like Ljuddämpningsduk type DURI dB WL 2mm or ACOUSTIC SILENCE 700, 2mm instead (same product). My thought is to place it between the particle boards. Am I thinking correctly here, or will there be no effect when pressed between two heavy boards? Is it better to stack the boards, glue/screw them so they become a very thick unit, and then place the mat between the particleboard and parquet instead? Is a footstep noise foam a better choice here??
The budget doesn't allow for using a duri mat both between the particle boards and under the parquet, as it's really expensive. Possibly, if you place it between the particle boards, I could afford a slightly better foam under the parquet instead of felt paper.
This is also the maximum height I can build the floors, so adding more heavy boards like floor gypsum, etc., is completely out of the question. I'm already pondering how the staircase should be adjusted to achieve the right step height.
