If you check the audio graph on your system volume, you'll see there is no hidden sound. Every time he stops talking, the volume drops to 0.

I think it's lost in the recoding. Watch it here http://www.youtube.com/watch?v=8nH2iuXrxKk at 480p or higher and you can hear it.

i got good enough hearing, i can hear ultrasounds with ease, problem is this is bull, during the song there was no sound, also normal humans should NOT hear high frequency sound on a regular basis (research prove that 60% of the population can't hear HFQ sounds and that excluding old people witch have bad ears anyway, children usually hear them and after you pass a certain age they won't hear them anymore) do some research before you get fooled

I have tinnitus after a tire exploded in my face, i could not hear a thing except the constant eeeeee sound 24hrs a day 7 days a week 365 days a year . I had good hearing and this tinitus is the most annoying of them all,strange because you're going deaf but you hear is a constant annoying sound in the background ALL the time.

lol, I heard at loud and clear in that youtubevideo. You should really check your hearing if you can't hear it, (if you not are like 70 yrs old :)

#6 Could heard it on 144p aswell as 240p and above.

Also i can hear the high pitched sound the old CRT tv's produce, so i can hear if someone is watching tv behind a wall/door, even if their volume is on mute.
I asked someone if they can hear it too, but i seem to be the only one.

Yep on YouTube link I can hear it and yes it is annoying why do i waste my time with this stupid test.

My speakers block that frequency, which is not surprising as a lot of speakers have a cut off frequency at around 15kHz. Anyhow, if you don't hear anything, unplug your speakers, maybe will the ones in your laptop work.

That is true #17 it comes down to the speakers (and equipment) as well at certain times. Tho in this video, the sound was prob up there, but below 15k i guess, far from above, as i could hear it on my shitty JBL desktop speakers, loud and clear.

This proves nothing.....the frequency in this test has nothing to do with good (or bad hearing)...It is normal for people to not hear this frequency, especially if they are older.

Yeah, if you don't hear the sound, you don't have 100% hearing capability, but probably more than enough hearing capability for normal life!

#17 If your speakers cut off at 15kHz, you have awful equipment. Most speakers can go well over 20kHz. It's your other equipment and processes that is cutting. Mainly, MP3 and other non-lossless compression methods block high frequencies because they contain a lot of information that we don't actually really hear. This is why this clip also works on Youtube, Snotr uses audio encoding that blocks too much (guys, seriously, audio does not take up so much space that you can't use better quality... Youtube audio is well compressed already, no need to rip their video and encode it all again.. before Youtube it's most likely been recompressed 5 times, do we need another round of quality loss?)

If you take a look at MP3 vs pure audio, you can see that even when encoding 320kbps, you are losing 90% of the information above 17kHz (doesn't affect me, i'm tested and that's as high as i can go anyway at this age). But regular speakers should go to 20kHz. Not very precisely but they will do that.

Most speakers can't produce lower frequencies, anything below 40Hz is starting to pose some serous physical limitations that make those last Herzes so expensive (or alternatively muddy DSP overdriving small cabinets, like most "hyperbass", "natural bass" etc PC desktop craps where you lose precision but gain volume..)
