Insulate interior wall

[Mwelander]

I have an interior wall that is completely hollow (free from insulation), it basically doesn't stop any noise, especially not from touch or if you plug in/unplug something on the other side of the wall. So I'm thinking of insulating it, and at the same time putting wood paneling instead of the current surface.

Would you open up the existing interior wall and put in insulation (complicated around any electrical boxes, etc...) or just add a stud on the outside of the existing wall and put insulation and a new surface there? It adds a bit to the room size, but the room is large, so it doesn't matter much if it's the easiest option.

I have an interior wall that is completely hollow (free from insulation), it doesn’t block any sound, especially not from touch or when plugging in/unplugging something on the other side of the wall.

It would build out a bit then, but the room is large so it doesn't matter much if it's the easiest option.

Based on the info I got in my thread about sound etc., I would open up, insulate, then close it again with 2 layers of drywall on each side. Also make sure it's sealed all over with caulk.
