In countries where they don't regulate noise polution, especially in bars where self-tought "audio engineers" will try hacking it by turning the amp up to 11.

Yes it’s more “identify” rather then “hear”, but could be useful for various applications.
I wish. This might be true if you are very young, but deteriorates rather fast.
In a related vein, I was curious whether this would be something miraculous that made humans hear the actual frequencies over 20kHz somehow, but it's of course the much more likely interpretation: High frequencies are aliased down into lower frequencies where you can then hear them normally.
Still seems to have cool applications, and if I understand correctly, it's going through great length to make the sounds still intuitively localizable, which must make for a neat experience.
