I ran across the word "Paracusia" yesterday, when I tried to look up the word for "things you hear in recordings that aren't really there". Paracusia is auditory hallucinations -- but that's not exactly what I wanted. I wanted those things on like Black Sabbath albums when you think you hear your name being called from the next room ...but you only hear it when you're listening to that spot on that Black Sabbath album. Your mind interprets a combination of harmonics with your name being called, sort of like interpolation (or is it extrapolation?). The aural equivalent of phosphenes (and to prevent Jacob from going into a murderous rage, phosphenes are those fireworks-like lights you see when you rub your closed eyes, because you're stimulating your optic nerve with nearby pressure).
So if anyone knows the word for that, I wouldn't mind knowing what it is, my google-fu failed me.
