Found an interesting Youtube video on practical wall construction. Anyone here have experience with this sort of thing?

instead of 2 layers of drywall. use mdf for the first (inner) layer
- much higher density. resiliant channel or accoustic glue are both
good. Isolating the second wall from both floor and ceiling helps.
Mount the wall to the floor using a "dri-core"base - doen't hurt to
use it between the top sill and the ceiling joists above either.

The difference between rock-wool and fiberglass IS significant.

The two important things are MASS and ISOLATION. - and of course
isolation includes ELIMINATING gaps.

As far as the heat ducts are concerned just insulate well around them
and make use of "baffling" - don't have as traight run from one room
to another make sure the sound needs to go around a few corners and
make sure to "damp" any flat sided ducts. to absorb as much sound
vibration as possible. A large thin rectangular duct can act as an
AMPLIFIER of sound by re-reflecting it. Damped, the sound does not
bounce.

Even installing a second stud system of 2X2 or 2X3 staggered between
the 2X4 studs fastened to the same sills, spaced out 1/2 inch so the
drywall is fastened to different studs on each side makes a big
difference without taking up as much space. - and using accoustic
cement to fasten the drywall instead of screws or nails also helps
decouple the sound. If the joists run between the 2 spaces instead of
parallel as shown in the video, install baffles between the joists -
tight fitting MDF or plywood covered with a foam-board works good -
even just 2 inch foam board is a lot better than nothing - seal the
joints between the baffle and the joists with spray foam or a good
relilant caulk. For the ceiling, building a second framework,
attached to the studs of the INNER wall and not to the joists above is
also a good idea. a few hanger wires mid-span attached to the joists
above don't degradethings very much if required to prevent ceiling
sag. The ceiling "joists"only need to support the drywall and any
insulation - and can be "staggered" between the existing joists to
reduce the loss of room height..

If using a complete second wall system the second ceiling framing can
be connectes only to the inner wall, and the inner wall can be
completely "decoupled" from the ceiling. That's how a friend's home
recording studio was done. - with the floor sitting on 2 inch
"styrofoam SM) , and the walls built on top of that, withthe ceiling
attached to the inner walls only, and the gap filled with blown
rock-wool. A bomb could go off in the next room and you wouldn't hear
it (double doors too,of course)

Makes more sense to use block walls and concrete floors, even for the floor
above the basement.

Nah. But this guy is a good start. Just be sure to look at other ways to do it.

Many years back, we added onto our two story frame house to build a home
office that I used for a professional practice. The contractor built
about an eight inch dead space between the new office and the existing
house then filled it with rock-wool- floor to ceiling.

Works great!

In my old church, I installed an organ blower from 1947 which was
completely clad in lead. You could barely pick it up!

Your previous questions you have asked. You were given answers to those
questions, do you not think we deserve to know what you did with them?

You are better off ignoring the trolls than responding to them.

NO. They do help sound in a room by breaking up reflection times.
