So I have got space for a home studio, but I don't know anything about isolation. My plan is to build a room inside the current room.

But I'm not sure if this would be effective, and if it is effective, would putting stuff between the 2 rooms (like Rockwool) increase the isolations.

I also have a lot of eggbox foam, where do I apply this, and does it help?
