Soundproofing...

General rule: As Norton says, standard fiberglass in a wall or ceiling is good stuff. In a ceiling, not much sense going past R19. Filling all the way with R30 won't give appreciable improvements.

If you are talking about soundproofing rather than room treating, you are going to have to buy sheetrock and build a room within a room. You'll also need green glue to go between doubled layers of 5/8" sheetrock. Anything less than that and you will hear each other pretty annoyingly next door.

Room within a room tutorial. May be of some help.

Wow - that is exactly how I built my basement studio. You guys did a great job on that.

One thing though - you might want to put a double solid door assembly on there also.

If possible, consider using solid core interior door slabs. They're heavier, as they're particleboard filled rather than foam filled.

THIS.

I ended up removing four steel exterior (foam-filled) doors and replacing them with solid-core wood doors. The steel doors were resonating at certain frequencies and I just wasn't happy with the isolation. I sold all the steel doors on craigslist and got the solid core doors instead. Yeah, it cost me an extra $150 and a few extra hours of work, but the benefits far outweighed the cost.

Nice Nate. Thanks for that assessment.
