I am enjoying thinking of this as an old person thread given most 25 year-olds cannot hear beyond 15kHz.
And actually, this has been a pet theory of mine for some time now:
It has been long known that people in the 'Spectrum find it difficult or impossible to read facial expressions and body language. In a loud environment where someone is speaking to you, a "normal" person can fill in the blanks in the person's speech with lip-reading, so while they may not actually be able to HEAR what the person said, they understand it because they can read lips. I can't read lips. At all. Like, when I was a kid and all the other kids could talk to each other by lip-reading behind the teacher's back, it was impossible for me. So for me (or someone else in the 'Spectrum), if I can't actually hear what is said, they might as well be speaking Chinese... That's my theory anyway, but based on the known limitations, it seems like a very reasonable one. I'd like to see a test to determine this with normal people, with the same speech impeded by background noise with no video of a person's face while speaking, and that same audio played WITH the video. I'd bet "normal" people would test much higher in this test in recognizing the speech buried within the noise by being able to lip-read.
