Elevick, You completely misunderstood my post.
by 'stagger' I mean that there are 2 sets of studs, not studs at random intervals. Both sides of a dividing wall are NOT attached back to back on the same set of studs. This will couple them 100%.
Instead: try building 2 half-walls back to back. Total thickness should be maybe 6" using 2x4 studs. 1 set is covered by sheetrock facing room 'A'. A second set of studs *between* the first set and offset about 2" are used for the 2nd wall, being room 'B'. Weave a dense sound insulation/damper BETWEEN the 2 sets of offset studs.
The 2 walls are now decoupled..bass and have insulation between them...for HF.
BOTH walls will be 16"oncenter, but offset 8"......
Man, I wish I could attach a simple drawing!
