IMHO no-one can prove what can be felt by the body or not, & if it ads or not to recreating the illusion of a live sound, perceived by the brain as more natural.

Poll Results: Can you hear sound over 20kHz?
The frequency range is not an even scale. It doubles with each octave. So the difference between 20Hz and 40Hz is exactly the same as the difference between 10,000 Hz and 20,000 Hz. When you are talking about the difference between 20kHz and 21.5 kHz, you are talking about a single note's difference on a piano. 15kHz to 20kHz is four notes.
If you are "feeling" a high frequency note by turning up the volume, you aren't necessarily *hearing* that note. Everyone can feel sound pressure from inaudible frequencies if they're loud enough.
The middle of the frequency range is what matters. Don't worry about the stuff only bats can hear.

Male 24 and I can't hear anything above 17khz
Kind of depressing :(
Guess I'm paying for the volumes of my teenage years (not only headphones but target shooting with .308s and playing large guitar amps with no ear protection, etc).

Hmm, in a very strange twist, even though I hear nothing from 17-20, I hear 21 khz extremely clearly. I verified this with the tone generator and slow, massive frequency sweep in my DAW. I mean, I hear 21khz more easily than I hear 15khz.
There's just a complete hole from 17k through just below 21 then it comes back for 1000hz clear as a bell, very strange.
Moral of the story: shoot with earplugs

Am I mistaken when I google lowest audible frequencies and read that most people stop hearing at 20 hz? Wow. I hear practically the same volume from 0 hz through the entire spectrum up to 17 khz
I need to get a job on Dune listening for sandworms or something
