Minimal amount of noise reduction

A lot of noise reduction.

Not really only from fiberglass insulation unless also did something
about separating studs, etc., ...

I agree, you only get minimal noise reduction unless you build a wall
with 2x6 top and bottom plates and 2x4 staggered studs so you have 2
isolated drywall panels on each side. *This is the proper way to build
a sound-reducing wall with normal building materials:

Top down view of staggered 2x4 studs on 2x6 plates, then you insulate
for maximum quietness. *This is a great method for home theatre rooms,

Well I can see my ascii art work failed because the text wrapped.

But the idea is to build 2 isolated 16 inch OC stud walls on 2x6
plates with 2x4's, offsetting the studs by 8 inches. Sound will not
transmit easily because one sheet cannot vibrate the opposite sheet
because there are no common studs that hang both sheets.
