@ghdprentice You got at the heart of it, first, when you said, "The problem is the measurement problem is so oversimplified… it does not come close to characterizing sound as heard."
In early psychology, there is the idea of "minima sensibilia," roughly the threshold at which some phenomenon can be sensed. If we had that for audio measurements, it would help -- somewhat. I'm convinced that there is much we hear that no one knows how to measure for, yet. Skeptics will say this is just "subjective bias" but that catchall move just ends inquiry, cold. There's more at work, I'd expect.
