My God.
I am awed.
Talk about an out-of-the-thin air serendipitous discovery that moves a grown man to tears, it's so wonderful.
Welcome to the inside of franksolich's skull, because according to professional audiologists, the sound replicated here, as heard by hearing people, very closely matches what's "heard" by me through conduction of sound through the bones.
https://youtu.be/hPRYZ8eAW34The "sound" of music boxes, of course. When I was a little lad, the parents use to visit an elderly woman who in her bedroom kept a large collection of antique music boxes. While the grown-ups were chitchatting in the living room, as soon as I could, I wandered into the bedroom, where I sat on the edge of the bed, playing the old music boxes, "hearing" them by pressing them firmly against my forehead, or under my chin against my throat.
This bothered the parents for two reasons; first of all, it was inappropriate for me to go into a private part of someone's else's home, and secondly, they were bothered by my insistence of "listening' to something over and over and over again, for hours if I could get away with it, thinking this sort of compulsive behavior betrayed a mental disturbance.
Which of course was nonsense; I was merely trying to "imprint" the sounds into my head for future reference. To this day, decades later, it creates an awkward social situation when out with others, and I encounter music boxes. I immediately forget who I'm with and what I'm doing, just to sit there, "listening" over and over, to the exclusion of all else that's going on around me.
Most people, including even best friends, consider this excessively bad manners, but I say to myself, "**** you--you can hear at will, on whim, and when convenient, while I'm compelled to take every opportunity given me--and it's not given often."
