ᐅ Roof beams as a sound bridge?

Hello!
In a converted attic, two rooms are separated by a drywall partition. On this drywall, there is an additional soundproofing wall plus a layer of foam absorber. Nevertheless, a considerable amount of noise can still be heard.
Two roof beams run through this partition from one room to the other.
Does anyone have experience with how much these act as sound bridges? And most importantly, how to prevent this?
Thanks and best regards

I am not a building acoustics expert (only in engines), but I think the beams are probably not the issue. It is more likely the floor, incorrect installation of the drywall partition, or even the soundproofing wall. The latter probably only prevents reflection or echo in the room where it is installed.
