Going to disagree with your analogy here. A high pitched sound will work with the ear in the normal way and be processed the normal way. There is no ignoring it (without ear muffs).
However, jelly-scrolling does not effect at all how I interact with the mini. I use a mini like I would a book for reading, or a tv for viewing. I don't read pages as I flip them, and I never shake my tv while watching a movie.
Likewise, on my iPad mini, I scroll with only minimal processing, stop. read. scroll again. No impact on my knowledge gathering from jelly-scrolling. Its even simpler when viewing YouTube or a movie to totally ignore the jelly-scrolling. And yes, if I look for it by rapidly flicking pages back and forth I do see it. thats just not how I use a mini.
Whereas a high pitched sound, well, that I can't ignore as easily.
Jelly-scrolling is a reality of this type of screen. It's just an easy to ignore one for most (but apparently not all)
