Default Owens Corning QuietZone -- marketing ploy

"Actually it is pretty easy to tell whether regular insulation
does anything. Just go up in the attic and have
someone hollar up at you. Then lift a batt out of
the way (or move the blown in insulation to the
side and have them hollar up at you again. Course
you could just put some music on your Hi-Fi to
test the effect. Has hardly any effect"

That it has some detectable effect at all would be fairly positive
proof that it does in fact work. For your test, you are only removing
one batt, a small percentage of the total insulation in the ceiling.
The rest is still there and contributing to the sound reduction. To do
the test right, you would have to remove all the insulation and then
measure the sound difference.
