Absolutely fascinating!! Any penny that bright can get thrown on the tracks can't happen often enough. Do you mind sharing your background to have that knowledge?
I'm just a guy who is really interested in how stuff works, and that includes the science of perception. You know, we live in this hobby with this objectivist/subjectivist battle sort of bequeathed to us 60 years ago by J. Gordon Holt and Julian Hirsch et al., but our ability to measure sound, and especially our understanding of the science of perception have changed so much in 60 years, it's kind of mooted that whole divide for me. I read Daniel Levitan's book This Is Your Brain on Music when it was published in 2007, but I really didn't start reading in the science of hearing and psychoacoustics until after watching an episode of Nova called Perception Deception, and realizing how far the science had come and how little I knew about it (in fact, when they teach the general basics of how hearing works to people, it's so oversimplified that most of us, and certainly I previously, have a faulty understanding of it).
I've also been a musician for most of my 61 years and done a bunch of audio production work, so I knew how to make sounds, yet it seemed like I understood very little of the "last mile" of sound -- hearing and auditory perception. So, I've just been learning it a little bit, through reading Brian Moore's classic primer, An Introduction to the Psychology of Hearing, through reading some of the work of and listening to lectures by the likes of Stephen McAdams, Nina Kraus, Susan Rogers. I'm just barely a beginner in the subject, but I've learned enough already to realize there are a lot of common misconceptions and widely held partial understandings.
