In my experience, yes: as soon as I willed myself to move my head, the sound disappeared. But unlike these people are reporting, it never reappeared in the same session. Nor did it have a "structure" in space: it just happened when I regained consciousness.

I remember one trick to get out of sleep paralysis was to turn my eyes (you're always able to open your eyes and look around) and head until the movement was big enough to snap out of it. Once I got out of it and I didn't move much (like if I just turn around in bed) it could easily happen again. The best way to avoid this is to try doing something that requires concentration, like getting up and do something that requires concentration for a minute and then go back.
