Rockwool for sound deadening

I have a friend that is building a new house and inquired about some sound deadening. His living room & master bedroom adjoin each other & share the same wall. The walls are still open and he wants to do something to keep down the sound transmission between the rooms. The house has 10' ceilings and the wall length is probably 15'. The walls are up but still open at this point.

I told him the best bet that I knew of was Rockwool. Do you have any other suggestions? Its not full sound proofing, but should help to some degree.

If we use the Rockwool, what do you do to keep the material contained in the stud cavity before the drywall gets installed. What prevents it from sagging now & then afterwards thru the years?

Your help & suggestions are greatly appreciated. Thanks Mike

It might be easier to use soundproof drywall like Quietrock.

take a look at ultra touch, thats the blue jean insulation,

I installed in our basement ceiling and I cant believe how effective it works when the kids have loud gatherings down there!

More options open with the walls not finished including building two separate walls, adding insulation or mass.
