Hello everyone,
We have a solid concrete block house made of aerated concrete (Ytong) and chose a wall thickness of 36cm (14 inches) between our bedroom and the children’s room instead of the originally planned 16cm (6 inches). Unfortunately, since our TV is placed directly against the wall to the children’s room, almost every word from the TV can be heard on the other side. We’re now hesitant to do anything else like watching TV in the bedroom to avoid disturbing the little ones.
What options for additional insulation between the rooms make sense here? So sticking egg cartons to the wall is out of the question. We have considered whether it would be sensible to install a drywall partition in front of the existing wall and insulate it with mineral wool to achieve the desired effect.
It might also be important to know that the entire floor on this level is installed continuously without gaps at the thresholds, and the ceiling above consists only of drywall, a vapor barrier foil, and a layer of insulation wool, with the open attic directly above that. Therefore, I’m not entirely sure whether the noise transfers mostly through the wall, over the floor, or through the ceiling and where the best place to start would be.
What do you think?
Thank you very much,
Martin

Do you perhaps have a mechanical ventilation system for living spaces? No. No residential ventilation system because Ytong without thermal insulation.

(Ytong) and we deliberately used a wall thickness of 36cm (14 inches) between our bedroom and the children's room instead of the planned 16cm (6 inches) The problem is that Ytong, with its apparent density below 0.7, is simply not suitable for such applications. For child safety reasons alone, I would never design parent and children’s bedrooms directly adjacent to each other.
As already mentioned, install a drywall partition in front of the Ytong wall—apply drywall twice, preferably three times—and add insulation behind it. Make sure the stud framework does not have direct contact with the Ytong wall. It may be worth considering this on both sides of the wall.

If necessary, consider both sides of the wall.Something is definitely off here. It doesn’t make sense to seriously aim for a wind load equivalent to half a meter (36cm (14 inches) wall + plaster + studs on both sides + double or triple sheathing).
There must be thermal bridges or something similar present somewhere.

As mentioned... the ceiling height is about 2.60 meters (8 feet 6 inches). Above that, the wooden roof structure. Above that, a vapor barrier and then a layer of insulation wool (cold roof). Below, drywall fixed to aluminum rails. The collar beam layer is your sound bridge – there’s no need to mess around with the 36.5 cm (14.4 inches) Ytong blocks. Which I consider somewhat misused for an interior wall anyway...
