Ceiling insulation / sound transmission

[sxx]

Dear studio designers,

I'll start building my studio very soon

I would like to make sure I'm not doing anything that would compromise ceiling's insulation(like a triple leaf).

I'm going to build the studio (room within a room) in the ground floor.
The studio's ceiling is made of 2 layers of 12.5mm Fermacell (drywall).
It will be held to the joist using resilient channel (Rigips).
Between the studio's joist, I'll add rockwool (8cm)

The room above is equipped with an underfloor heating system sandwiched between 2 OSB layers and then the floating parquet.
Here's a schema of what I'm trying to explain.

Is this ok or am I doing something wrong?
Thanks in advance for your help.

Technically, that looks like a 3-leaf system, but with the large cavity depths in there you should probably be OK. However, it would be good to know what level of isolation you are planning for (in decibels), and what purpose / type of music / instruments you'll be using the room for.

Hey Soundman2020, thanks for your answer!

I'll be producing mainly electronic/ethnic/chillout music down there between 80 and 100dB.
The room above is my yoga/meditation room so I'll try to have the maximum insulation that I can have with my (limited) budget.

There's more details about my building plans here, I'll be very thankful if you could have a critic overview on it
