Floor construction with underfloor heating at exposed timber ceiling regarding sound insulation

Hello dear community,

for our new building, we are planning a two-story building with an exposed wooden ceiling (rafter spacing 60cm).
The currently planned floor structure is:

- exposed formwork
- 15mm OSB boards
- Roth edge insulation strip 160 x 10 mm
- floor insulation plate EPS 040 DEO dm, 50mm
- Roth composite roll 30-2 PS-TK 5.0
- Roth system pipe PERTEX Ø17 mm in stapler system
- heated screed (cement screed) total 65mm
- partially tiles and partially laminate with RENOVO Aqua stopp 1.6mm for underfloor heating

My question regarding this is:
Is this structure sufficient for adequate sound insulation?
Do we need to work with more mass here (e.g. concrete slabs or higher floating screed)?
Any other opinions about this structure?

We want to prevent that all noises or footsteps from above are heard very loudly downstairs.

Thank you very much in advance for helpful hints ;)
