Background: Georgian flat; Bedroom stud wall that is shared with communal stairwell; There is one fixed door (not in use) between the bedroom and stairwell hall.
Issue: On either side of the wall, it's in lathe/plaster; however, on both sides, 30% of the wall is not covered with lathe/plaster as there was a wood panel along the bottom end of the wall. The panel is now just cheap, thin board installed 12years ago by lousy contractors (of previous owner). I don't own the exterior side of course, so focus on the interior side of wall.
I hear EVERYTHING. As I see it, there must be noise travelling via the door (either through it or in air leaks around it; And, since the lathe/plaster does not cover the whole wall, the sound benefits of lathe/plaster are compromised (understand a regular lathe plaster wall is pretty good for sound blocking).
Question: How to soundproof?
I am aware of two approaches: Applying a 20mm thick rubber panel (SS20), and then two acoustic boards. This is all glued against each other. I understand that putting screws through the layers against the studs would not work as sound travels via the studwork. (and acoustic wool between the joists). This means I take off the lathe plaster that is there (80% of the wall). I can't see what the lathe/plaster serves as so much of the bottom is not there, and, I'm gaining back about 30mm which is needed.
Or, a resilient bar system where the bars are added and then acoustic plasterboard (2 sheets). Either way, I am going to cover the fixed door from the inside, likely with the same materials used for rest of wall.
I can compromise on many things, but not communal stair way chatter entering the bedroom. Of course, there is some noise from footsteps on the staircase (carpeted) and I could get the freeholder to add some acoustilay to the steps, but I really think this is a lost cause as I'm sure the vibrations are being transmitted in every direction, including the floor joists and then over to my bedroom. So... likely not much one can do here.
Thanks very much.
