Many of these questions and more have been answered at the Super Soundproofing Forum at http://www.supersoundproofing.com

Specifics of soundproofing doors is at

The numbers mentioned refer to the STC of the assembley. STC means Sound Transmission Class, a number assigned through lab testing measuring a products ability to reduce sound. The higher number the better.

Be careful with those bandying about STC numbers. The items may not have been tested or the lab is suspect, or even no lab, just a software program making an estimare of it.

MLV (Mass Loaded Vinyl) and "Green Glue" have become the standard products for effective sound control - Google them for more info!
