My Soundproofing Journey - Soundproofing a Master Bedroom Shared Wall in a Duplex (Side A): Part 2

This is Part 2 for Side A in a series of videos in which I document, from start to finish, a soundproofing project for a shared wall in a duplex. I have separated the videos into Side A and Side B, as I made modifications to both sides of the wall, but you will be able to see the effect of just the Side A modifications. Side B obviously begins with the completed Side A as a baseline. The primary difference between the two sides is that I removed the existing wall on Side A, reinsulated, and installed a floating wall, whereas for side B I left the original wall in place and added another layer of drywall with Green Glue. This is a VERY detailed look at the entire process, so not for the ADD crowd. I created this series because in doing my research, I found very little DETAIL about soundproofing, and very few ACTUAL RESULTS. Here I will attempt to provide both, so that someone who is serious about learning how to soundproof a wall can see what might be required, and what real-world results could be gained through various techniques. The videos in these series are as follows: Part 1 (Side A): Investigation and 'Before' Measurements:    • My Soundproofing Journey - Soundproofing a...   Part 2 (Side A): Removing the Wall & Acoustic Sealing:    • My Soundproofing Journey - Soundproofing a...   Part 3 (Side A): Installing Insulation:    • My Soundproofing Journey - Soundproofing a...   Part 4 (Side A): 'Floating Wall' Construction:    • My Soundproofing Journey - Soundproofing a...   Part 5 (Side A): Acoustic Slat Panels and Final Tests:    • My Soundproofing Journey - Soundproofing a...   Part 1 (Side B): Wall Preparation:    • My Soundproofing Journey - Soundproofing a...   Part 2 (Side B): 2nd Layer of Drywall with Green Glue:    • My Soundproofing Journey - Soundproofing a...   Part 3 (Side B): Acoustic Slat Panels and Final Tests:    • My Soundproofing Journey - Soundproofing a...   Products used for Side A of the wall: 5/8" Type X Fire-Rated Drywall Rockwool Comfortbatt (5 1/2" thick) MarvelMute Full Rubber Isolation Clips (from TMS Soundproofing) Hat Channel (from TMS Soundproofing) Acoustic Caulk (from TMS Soundproofing) Putty Pad (from TMS Soundproofing) Acoustic Slat Panels (Artika Sonolok 2x2 panels) Products used for Side B of the wall: 5/8" Type X Fire-Rated Drywall Green Glue (from TMS Soundproofing) Acoustic Caulk (from TMS Soundproofing) Acoustic Slat Panels (Artika Sonolok 2x2 panels)
