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

Mottenhausen14 Jan 2019 14:51A 36 cm (14 inch) interior wall should generally be fine. How is the TV mounted? Is the sound being transmitted through a wall mount to the wall, causing it to vibrate? There are decoupled wall mounts available for situations like this. Try testing by simply placing the TV normally in front of the wall; if there is no noise then, the wall mount is indeed the issue.
