I have a small office room that shares a wall with our living room. When we have guests over, their voices travel fairly well; they sound somewhat muffled but are still audible. As I WFH occasionally, I'd like to reduce any/all noise as much as I can.
I'm not sure where exactly the noise is coming from... we do have central heating air ducts but the register is on the opposite wall... there's not much of a gap for the office door... maybe it's just coming through the wall itself?
Oddly enough, if I check sound levels from the adjacent room (on the OTHER side of the office), the noise from the living room is still there too (maybe a LITTLE softer but not by much).
Could someone provide some "sound-proofing" tips? Or perhaps ways to troubleshoot this further? I'm on a limited budget so I can't really afford to tear down walls. Not sure if there's insulation...
