There is a big roll of Mass Loaded Vinyl near the front door that can be applied to the metal exhaust ductwork on the lasers that should dampen the noise. I don’t have a specific plan on how that would get attached, so feel free to think that out.
Granted, the chillers and little air pump are more noise than that exhaust ductwork. Moving those are another task. Just thought I’d post this because we asked about that big heavy MLV roll and, yeah, we can just apply it and see.
