I have kids and work from home. I need a quiet environment in my home office and bedroom for romance. I tested with my HomePod and Apple Watch decibel meter. with the speakers at 80%, 76 dB was achieved from the door. Door closure without V-Bar application was 64-68 dB. After applying the sweep I had an average of 52 dB. Of course you can still hear the music, but it was a noticeable difference. and it was intense to hit the opening of the door with volume. The door jam was very tight and took a lot of effort to close, but this should lessen over time.
