High End Audio and Your hearing as you get older

 
On-line hearing frequency test from 8kHz to 22kHz in increments: But can you hear THIS?
 

Wow, now I'm going to sell all my equipment as I "can't" hear anything from 14Khz on up. But there is more to test signals than that. There has to be. I can hear instruments that play at higher frequencies on a regular basis but can't hear the friggin test tones. What's weird is that even on a low setting, the 8Khz test tone hurt my ears while the 12 Khz test tone was soft and really nothing beyond that.
I know this opens a huge can of worms but this goes a long way against the argument that only what can be measured is the sole criteria. So many flat earthers stick to their measurements with a fanaticism that borders on religion and yet I can hear things that I shouldn't.

Ballan,

Thanks for the TED link to Evelyn Genie. I hope to meet her one day - inspiring. I noticed they have a video with Benjamin Zander speaking about passion. Having met Benjamin several years ago I am sure that is well worth watching too.

Nonoise, are your sure?

Unsound,
I stand corrected. And humbly so. A quick look at some graphs clearly shows that only the pipe organ can play a fundamental frequency to about 15Khz!
Everything else barely hits 5Khz. But it's the harmonics that can extend things to beyond 16Khz. In music they always will since no one plays only test tones. Considering that, was I so far off or am I missing something?
