DIY Sound Maze Test for Noisy Above Door Air Vent

After building the sound maze, we explore the before and after. Did the sound maze actually soundproof the office? Was the difference worth it? Should you build one?
We test a 3-panel and 4-panel version too. Was there a difference between these two? Did either of these isolate the office from the living room?
Make sure you watch the first video where we built the sound maze if you haven’t already.
