No. I heard them so it make it automatically not special, according to you, anymore.

Yes, I heard them all. The first one freaking hurt! It was really loud.

I refuse to believe that there is sound coming out from the 17.4khz - either my earphones are bad, or my ears are bad- probably both

Can hear it all, I'm still young but that was kinda cool since my speakers are totally crap and it's nice to see them pulling high frequencies off.

I had the scare of my life when I couldn't even hear the first one only to realise the volume was off.

I can just baaaarely hear the last one and I'm 25. If I get close to the speaker I can hear it fine, though. However, my wife is nearly 29 and a half years old and she can hear the last beep perfectly from any distance. So... I feel horrible, lol.

Shoot. Can't hear the 17.4 out of my right ear, only my left.

Ah! That is still good, though!

I got to stop sticking the Wiimote in my ear.

Barely can hear the last one. But then I'm twenty two and a half, so only a year and a half off of the point where I'm not meant to hear it at all.

All the metal and punk concerts should really have left me more deaf than I apparently am

I felt really upset with myself when I couldn't hear the last sound (tried about 20 times)

And then I got the bright idea to turn up the volume a lot and I can safely say that last sound utterly pierced my ears. Never again.... Never again...

EDIT: I'm 22. So I guess my ears are still good. :P

EDIT: Fuck. I turned on my music after closing that video, with my volume still extremely loud, and almost had a heart attack. For a second I thought my monitor was going to fall over. Bad dubstep music.. bad...
