Two small windows 4" thick with triple pane. 3" thick solid wood door, mahogany on outside, pine inside. Whisper quiet mini split AC/heat wall mounted unit.

Result is stunning, I hear nothing from the outside, trash truck included, and no one hears a peep of my music from the outside, no matter how loud.

Mission accomplished for sound proofing. For acoustic treatment I worked with Gik and the results are phenomenal. It took me 3 months to tweak in the system and now 6 months later I have completely stopped tweaking anything. Happy and satisfied music lover here with what I accomplished. The construction was nerve wracking at times since no one around this area was familiar with this type of construction, but I really enjoyed guiding those guys along. Great experience. In the process of upgrading some equipment, pictures will follow. Ended up doing a bunch of acoustic treatment upgrades also. Reality is the journey is never over no matter the level of quality. Lesson learned :)
