Hearing a 20 Hz frequency is weird too. I have trouble imagining a membrane moving at 20 cycles per seconds and hearing a continuous sound out of that.

 Oh I know what you are talking about! Haha, it used to annoy me in my small campus room when my focus shifted and made me start hearing my router communicating wirelessly with my laptop computer: an intermittent, high frequency tone, but very low and insidious and once you have set your attention on it it's very hard to "forget" it is present!

Now I have moved and the fridge I have makes more noise and overall it's more noisy (well, from a silent low dB to another silent low dB, because I love to do my homework in silence and I make sure I have it when I need it) and I don't know, but I don't hear it as much anymore.

 

Gosh it annoyed me in my first semester.

Well in the game those are used as trophies and I don't like to die or admit myself defeated (and it was a pun too :P). But don't feel forced to keep it, I wasn't such a worthy opponent.

I'm 20 and could hear up to 18 KHz. 

 

Pardon my ignorance, but are there actually any sounds over 20KHz in music? Or is there a lot of stuff going on in music that nobody hears?

There is some sound over 20 kHz, but nothing really important, only harmonic overtones of instruments (that have a much lower fundamental frequency), and noise from cymbals etc., however normally nothing at very high levels. But you can check it yourself by opening some lossless format music in a sound editor, and viewing the FFT at parts where you think a lot of high frequency content is likely, and experiment if filtering it out makes an audible change.

male, 27, according to youtube tests 2hz to 19khz

I don't trust those youtube links, but I've used some tone generator plugins and found out that I can hear up to 18,000 Hz. I'm a male and I'm 19.

Erm... You guys actually have loudspeakers/headphones that are spec'ed to be capable of emitting >20kHz sound?

 

On a related note, it turns out I can't hear 14kHz and above, yet I'm only 29. Either something is very wrong with my ears or the MacBook Pro's speakers are really crappy - the latter case would still be the lesser of two pieces of bad news.

I'm15 years old right now, my doctor says that I have a excess build of lipids near my eustacian tubes so I am hard of hearing right now

I would try something other than laptop speakers first, before you start shopping for a hearing aid or something.

 

Most headphones will play 20 kHz, just not necessarily loud or clean.

Have you tried raising the volume more? It seems everyone can here anything if they raise the volume enough. By maxing my amp I heard the 22 kHz at mosquitosringtones well enough (even though I can't hear past 17 kHz on normal-to-loud listening levels)... with a capable headphone, of course (Fostex T50RP).

Male, 17, 17.4KHz
Protip: Use hearing protection when shooting firearms. Or, You'll lose 3KHz of hearing by the time you're 17.

I used a sine generator, as should everyone. Probably what you're hearing when you turn up the ring tone is IMD or some other artifact. Using LittleSine, I can hear up to 17.4 kHz in both ears at my regular listening volume (although it's quiet), but not anything above that at any volume. Steep cutoff.
