It's been my experience that most true audiophiles are more familiar with how to pull out their credit card than they are familiar with what good sound is.
well i wouldnt know for sure but i had met a few blind people who could hear/smell things that we could hear and smell but not to any Nth degree like they could.
im sure there are adaptations to the human body's senses when parts get disabled etc but i wouldnt have a clue what extent that is.

Oh man, don't get me going on my sense of smell. Sometimes i wish i couldn't smell anything. It drives my wife crazy. She is very modest with scented things, but I notice every little detail. No joke, she started using listerine the other day, which is a strong scent I know, but I smelled it from the other end of the apartment (two rooms and a long hallway) and she got frustrated, because she can't so much as open a bottle of anything without me complaining "what's that smell?" haha. But it really stinks. I smell smoke anywhere and everywhere when it doesn't bother anyone else. I sometimes feel like i can't just get a break from smells. :-/ Heaven forbid the neighbors below us decide to cook their foreign wet diaper food ugh... lol
It is very difficult to measure hearing at very high frequencies. Often what you detect is noise or distortion or chaotic cone breakup.
I think most people who report being able to hear above 20kHz turned the volume up to be able to do that and are either just feeling sound pressure or are hearing some sort of distortion in the audible spectrum because the spike in the inaudible spectrum is so big.
You guys must all have blown your eardrums. I can easily hear well over 20kHz. For example, I created a [.wav file] that plays a sweep from 11kHz all the way up to 44kHz and I can easily hear it the whole time.
Okay, now where is the trollface emoticon?
okay,, obviously I am being facetious. If you haven't yet figured out what I did, then you should check out the wiki article on aliasing and Nyquist frequency. Because the sample rate of the wav file is 44100 Hz, the nyquist frequency is 22050Hz, which means the part of the signal above 22050Hz is aliased to a sound less than 22050Hz; hence it is audible with this sampling rate. Okay, stop flaming me now, thanks!
Cheers!

I'd like to add that just because you can hear a sound at really high volumes doesn't mean you can really "hear" that sound. If you get a high sensitivity dish microphone like the CIA probably uses, you can hear a mail truck 2 miles away. Without it you probably won't hear anything. If you have the volume at max and barely hear a high frequency tone, you probably can't hear it at regular volumes and especially not with other tones (music) getting in the way. So I would argue this test is only valid up to regular listening volumes, even if those are loud. If you can't play a song at the same volume, it's not really proving anything. While you technically can hear "some" amount of that frequency at "some" volume, in 99% of cases you wouldn't actually hear it. I think that all made sense.
I confess, that I can only hear the highest tones at louder volumes. I can probably hear between 18.5-19.5khz without raising the volume louder than a loud song. And my audiologist was very impressed with my hearing tests and noted that I passed the tone tests with 100% accuracy even at the quietest volumes. He hadn't seen that before. So, unfortunately, without a proper testing environment, capable equipment, etc. it's probably impossible to really know you're actual hearing limit. I would guess the average limit is around 16khz with some good ears up to 18-20khz.
I used to service some ultrasonic scanning equipment and I could absolutely hear that. I have no idea what level it was but I am sure it was pretty high. We were supposed to wear hearing protectors when we were working on it. Now that I am older I am sure I couldn't hear it today though.
