ᐅ Sound Insulation – House Very Noisy Between Rooms!

Hello everyone,

we have purchased a house built in 1996, constructed with solid building methods. However, the upper floor is incredibly noisy. My daughter’s room is right next to our bedroom. She has a large gable in her room. When she simply plugs in a charging cable, it sounds as if it is happening in our bedroom. If she talks quietly, we can hear every single word. What can I do? What needs to be checked, and who or what type of company is the right contact for this? It is really very loud and driving us crazy.

If the sound is coming directly through the walls, you could consider installing a drywall partition with mineral wool insulation in between. That should help reduce some of the noise. It’s different with sound that travels through the floor, though. I’m not sure if anything can be done with the flooring material to address that.

I hope you manage to solve the issue. Otherwise, it might just come down to some “togetherness” when your daughter stays over at a friend’s house or possibly at her grandmother’s place... and so on. 😉

It’s not just about our time together… it’s really annoying. When I go to bed earlier and our daughter is watching something on the iPad or similar, I can hear everything clearly… could this also be due to the gable? The walls of the gable sound very hollow when you knock on them…

It’s the same for us (gable). We also have a solid construction method (aerated concrete). Aerated concrete is said to have poor sound insulation. However, we don’t find this to be overly noticeable. As mentioned, if sound passes directly through the dividing wall, a drywall partition might help. I’m sure the experts here will provide more answers 🙂

We had neighbors with the same problems; the cause was drywall made with the thinnest gypsum boards without insulation, which you can’t see. Either do it yourself or hire a drywall contractor—most likely a complete redo is needed.
