ᐅ Leveling an Old Wooden Floor with a Screed or a Timber Substructure?

SaphyroxHello everyone,
We are currently converting the attic. The floor consists of old wooden boards and has a height difference of about 8-10cm (3-4 inches) over a length of 10m (33 feet). Additionally, the floor sags slightly in some areas. At the moment, we are looking for the best way to level the floor. It is also important that good sound insulation to the rooms below is provided, as it is quite noisy.
Our options currently are a screed filling, on which Fermacell boards would be laid, or a batten structure recommended by a carpenter. This involves installing a wooden grid made of two layers of battens across the entire room, forming grids measuring 40x40cm (16x16 inches). This structure is installed as a floating floor and leveled to the room height. Under the support points of the grid, a type of resilient felt is placed to minimize sound transmission. Felt is also placed inside the 40x40cm (16x16 inches) grid spaces, slightly extending above the upper batten so that the floor rests on it. The carpenter is not very supportive of the screed filling, mainly due to airborne and impact sound, since it is not decoupled from the floor.
Does anyone have experience with this type of floor leveling, and is the screed filling really that permeable to sound?
