This was the only area I've soundproofed. You'll read lots of good info on soundproofing on VAF. Bottom line, real soundproofing requires mass, and I would rather build light and buy good headsets. However, this area looked like a drum to me so I built up some of the soundproofing foam mat (don't recall the brand) so it exactly filled the space between the door pieces, only about 8" square, to deaden sound in that drum and also stabilize it a little. Might have been a waste of time, but that's what I did. Probably not a big deal either way. Good thing is, it's your call!
