im 14 and i can't hear anything...
+Marissa Jean ditto
+Marissa Jean the same problem but i have 13 yars
Mad Cat realy i tryed 2 earphones 4 headphones and 1 Box dosent work
+Marissa Jean CZcams cuts off audio above 16KHZ (16000hz) during file compressing, thats why you can't hear anything.
yeah
I played this on my ellipse 7 and it worked fine. People say its an empty file when it's not. And most sound programs aren't programmed to detect this pitch at all
Guys Just open your windows sound mixer, and you will notice that this video has no sound at all. It clearly shows that the volume never exceeds 0db. If there was a sound that we couldn't hear, windows should still be able to pick the sound up and graphically show it in the volume control tab. ;)
also, it 480p - anyway all youtube videos get compressed again by youtube and lose some of the sounds
If you want to test such things, download some good wav audio files
Well I hear it
i hear it
what a load of bs. I checked it on my music software and there's definitely 18kHz frequency in the sound. Btw, I can't hear it but I don't say it's not there just because I can't hear it.
This one actually has no sound, I think CZcams might have compressed it or something.
It does, either you or your headphones are not capable of hearing the sound.
TurtleBlaster If you open the volume mixer you can clearly see that no sound is playing.
BoostedChimp69 Minsung The audio is less than a second long, it's just a quick chirp right at the beginning and then 29.99 seconds of silence. I checked audio levels on my computer, had my headphones at full blast with an amp, and everything, there's nothing beyond that first millisecond
i hear it with my headphones
No, your just deaf
Thank you for this comment. I went and downloaded an mp3 of the tone and I can hear it perfectly fine.
I hooked it up to an oscilloscope - NOTHING. This is an EMPTY audio file - to fool you. Chances are, however, that your speakers wouldn't reproduce it, and even if they *did*, you'd not have heard it. But BOO to the poster of this.
:-)
I used to be able to (when I was 22) hear alarm systems - they were at 18,400. They made me so nauseous that I had to walk out of the given store. Also, I could always hear a television (CRT) - at 17,200.
Now, nearing age 60, I can "only" hear 14,000. I always wear ear plugs when out in loud situations (even amusement parks), and I highly recommend it!
PyroSax thanks for actually checking this, but the main problem isn't the up-loaders file, CZcams REALLY likes to compress the crap out of the audio and most tones above 17 Khz get mixed with different tones and the whole thing either doesn't play or it's not a true 18 khz sound.
I measured the output signal with my oscilloscope! It is just silence. Tell all the people and cats out there to stop imagining things!
Know Your Science Well it must be broken, because real live people are hearing it. Stop accusing people
+Know Your Science same, this has no sound. I just recreated the tone and my audio system can certainly reproduce it and I can hear it, but this is a whole lot of nothing. Funny how strong the placebo effect can be.
Agree , there is no sound here , I can hear the irritating 17400khz tone , but here there is no sound at all.
Yay I can hear it. Thanks to you I now Know that I cannot hear 19000 or 20000 but I can 18,000 with the volume up and on excellent quality. I could not hear it with the low quality settings.
But this is exciting to me because the last time I did this it was on a different soundcard (same headphones) and I couldn't hear past 15,000. I'm actually relieved my hearing is not as bad as I thought. I'm 30 by the way. So 30 years old still hearing 18000. I've heard that's decent. but it varies.
There is sound coming from it. I'm 25 and could hear it fine. It's faint, but I can hear it fine.
I just confirmed that this does not actually have the 18000 Hz sound, as my PC's volume mixer doesn't register any sound when I play this video (excluding the negligible sounds at the beginning and end of the video)
Also, it's making my cat go crazy. And I don't think he's "bullshitting".
+P A N I C . Animals have a different frequency range haha, your cat must've been like what the fuck is going on
I heard it! But the volume was 100%
theres no sound dumbass
Yeah me too. It kinda hurts
Windows sound mixer reports that there's no sound at all above ~17.2k. That must be where CZcams cuts it off, so if you're hearing up to 17k+, you should try out other tests around internet.
yes I did now figure out how to set to 720 p and you are correct, it does allow 18 KHz thru. Thank you!. I also hear a side tone but it is way below 18 KHz.
anyone who said they heard it are just hearing their own ears ringing CZcams cuts out all sounds above 17 kHz.
I heared it no joke i repeated it to make sure, as i went up to 18100 in a hearing test
i hear it like i stop the video i hear anything i play i hear a pitch note
No I heard it
I tested it on my brother in other room and he can definitely tell if i have it playing or not.
I definitely heard it. It's not an empty sound file. It just sounds like gas.
that moment when you realise you can't hear this frequency any more :(
Me too ahah ^^
I could.
I have an actual level meter on my computer and it's not showing any sound coming from this file at 720p in html5 on firefox.
i can clearly hear this sound like zzzzzzz comming
***** I don't know what to tell you. I really do have a means by which to determine if there is a presence of any sound at all attached to video playback and so far as this video is concerned all signs point to no.
My audio system certainly can reproduce frequencies in excess of 18khz and nother that sound or any other is attached to this file. whether it's being filtered out via youtube's data compression or not I don't know.
Brendan Peery as u mentioned the meter it showed nothing on my meter too but in practicality i could hear and the reason ur not able to hear is cause ur too old i guess or impaired hearing (no offence) u should research on this thing.People of a specific age only can hear this for example this frequency can be heard by people below 30 or something.For me i cant hear 19khz but this freq i can because i am 22
Offering that you hear something when your computer is telling you there is nothing has me suspicious about your noise floor and line level noise. If you hear a hiss or a buzz and interpret that as the 18khz sound file then you are hearing something I don't hear.
Brendan Peery I played it through a pitch-shifter, halving the frequency to 9,000hz, and yowch, there's a definite tone. I can't hear the 18,000hz tone, but I can feel the pressure of it. Looking at the soundwave itself, it's not a sine-wave, nor is it even. It's only a third of the full possible amplitude/volume.
I have a mac. I couldn't hear anything at all at first with max volume. After plugging in my headphones I can guarantee you there is an obvious tone that stops when you pause the video. I am also 28 years old but have always had pretty sensitive hearing.
You need to be sure that your device and earphones/speakers can transmit at this frequency. Most phones cut out about 10kHz. The iPhones we tried cut out about 9kHZ. Try it on your laptop with a decent pair of headphones but turn the volume down to avoid damage to hearing.
First, unless you are under 20 and probably under 10 and have the volume up really really loud, you will most likely NOT hear a clean 18 KHz sine wave. If you have bad speakers or poor audio amplifier what you might hear is a lower harmonic.
Second, CZcams recently switched out its transcoder and retranscoded all videos and while this and many other hearing videos use to work fine at high frequencies, the new transcoder has effectively created a low pass audio filter which pretty much takes anything above 16 KHz out even at HD resolution. This is not the fault of whomever put this video on here. CD quality (44.1 KHz sample rate) audio SHOULD allow frequencies up to half the sample rate or 22050 Hz. I don't believe, with this new transcoding process, there is anyway to get true CD quality audio on a youtube video anymore.
However, no one is being scammed here. At least on purpose.
And no this is not my video nor are any of the other hearing test videos.
I can hear it!
I'm 44 and I can hear it fine on iPad but I suspect the poor quality speakers built into the device might have something to do with it.
I definitely heard that
25 years old, and i hear it =]
FUCK THIS SOUNDS SOO OOOOOOOO COOOOooOOOOoLLLLL
I have amazing hearing
I'm 67, and I can hear it.....faintly on my laptop. Better speakers would sure help!
ich hör so leichten unterschied wenn ich das video stoop und weiter mache
Oh that is weird... It's super faint, but definitely there...
35 and can still hear this close to my ears
This video has no sound
43 and can still hear it with HQ settings and volume up. That´s a relief. Or rather not, very unpleasant feeling 😄
@@Punki80 37 now...can still hear it 😂
faint but i can hear it very clearly
I'm 25 and I can still hear it. Can still hear when a tv is on in other rooms too.
Nope. There is no sound to hear.
A little static sound only. 18000hz will sound like a headache feels. My headphones are 12-38000 capable.
well then you really well wasted your money because maximum what can human hear is around 20kHz
Set the video quality to 720p and you will (hopefully) hear it.
I'm over 50 and I hear it fine
anyone else have a tone like this constantly in their head?
You might have tinnitus, might wanna see a doctor.
+TurtleBlaster its not tinnitus. I've looked it up on reddit and it seems to be pretty common. It's kind of like when you're in another room and you know a television has been turned on. it becomes more noticeable when youre in a quiet room. changes pitch when you bite down.
that's the definition of tinnitus, just a very light one.
darayneman Yea dude thats Tinnitus. Mine started at 20 and I'm 25 now and it will get worse if you listen to loud things. Go see an audiologist. Its totally T just a low pitch case. Seriously protect your ears so it doesn't get worse. The worst kinds are horrible and then sudden bursts ugh. Protect what you have! Also don't trust fracking reddit with medical advice lol. But also if it changes pitch when you bite down it might be TMJ induced T so I really recommend an appointment with a good ENT doctor. Though most people ignore going to the doctor now a days... Also no mercury fillings and keep your teeth healthy its all connected. I have seen many doctors for this so I know a bit but its hard to help people who haven't seen a good ENT doctor or orthodontist yet.
Im 15 I can hear it pretty clearly to be honest
Once you're past a certain age, you wont hear anything. That's what this test is for.
i am way older and can still hear it ..how come???
you cant hear this if your over 20 or have your settings below 720p
I can hear it with my headphone
I can hear between 55Hz and around 18 kHz, while I am already 26.
I only hear the low quality recording hum slightly in the background.
I'm 24 and I hear it perfectly.. listening on a galaxy s6, even at low volume. I'm not lying.. i even paused the video to see if the sound stops, and it does. But i never listened to loud music with headphones so maybe that's why lol idk
how do you set the quality to 720p on someone else's youtube video? Even youtube and Vimeo both admit that their transcoders effectively filter out anything above 16 KHz. If there is a way for the youtube viewer to set the quality it is not obvious to me.
i'm 16 and i can't hear it
I'm 17 and i can
I'm 16 too and can hear 16 kHz too. In fact i can hear up to 19.5 kHz. If you can hear it on this video, it's probably due to CZcams's lossy audio compression - which has a sharp audio cut off at 16-17 kHz.
16 can still hear full volume if I stuck the outlet in my ear lol.
omfg my ears .....
when i click on the different areas of the video i can hear this clicking sound, when i turn my volume up and down, its still there.
but theres no sound in the actual video that i can hear
so uhhhhhhhh help pls
i am 15 and i can hear this one
+Gabriel Hernandes Eu também não :(
I can only kinda hear it if I put my iPad speaker up to my ears. But I'm 25 with Tinnitus from an ear disorder and slightly deaf in my right ear from douch bag related air horn damage. Cant even hear whistling or rain in my right ear only deep sounds but for some reason can hear the electric buzz of my phone weird lol. But the T is bad. Smh.
i can only hear it at the end, like a faint pop
Damn. Had to crank my audio on that one. Just barely. I'm 50 but I'm also an audiophile.
Heard it at 720p. I am over 40.
I CAN HEAR IT XD, THIS ISNT AN EMPTY FILE
si lo escuho y tengo 25 años :D
My head hurts
Shane Dawson, I can't hear it but it hurts.
im 20 and i hear it
I can hear it now, but when I download it I can't. Does mp3 not allow 18000hz?
I heard in my cell phone 30 hz to 17k
I didn't hear it but i think it made my ears hurt... or it was one of those things that you think so your ming makes you feel it.
ow my ears jesus
From my meter, the side tone I am hearing is more like 1,7 KHz
Strange. First I don't hear anything. After the video end I heared that the sound left. Then I listened to this again an heared the sound.
I cant hear a thing and im youger than you!!
I can hear it
I'm 17 and I can't hear it
crappy headphones or ears
Ouço apenas um leve chiado.
idk what age has to do with this tone in particular, but it seems like lots of young people can't hear this, I'm 19 wearing earbuds and can hear it just fine o_O
My 24 year self, nor my 7 year old son can hear it. I seem to lose my ability to hear at 16khz.
I'm 10 and can hear it
Can hear something at Max volume using mx50
my ears hurt. and now I have a headache.
It's not real i just heared the tone from another source so yeah this is a scam
I can hear this with full volume and I am 12. This is the highest frequency I can hear. I can haar the mosquito(17,400 hz) at half volume
+TheDaveSiblings! "haar"
i can kind of hear it
Really???? I just tested this with a meter to be sure but I already knew that even if you did submit a video with 18 KHz in it, the youtube transcoding software effectively eliminates anything above 16 Khz. So I don't know what you people think you are hearing but it aint 18 KHz. My meter reads a slight spike at 11758 Hz (which would be annoying to some ears). No 18 KHz here.
I heard something but thats not 18 khz they are back round noise i think
Im 14... Can't hear it I'm scared
wtf are you dumb not all speakers can do it
I'm 13 ... Didn't hear a peep..
Qué extraño, pensé que era joda pero es cierto, si lo escucho perfectamente al igual que mi hermano pero mis padres no pueden...
I didnt hear it at first until I turned the volume up....does that still count?
U just heard speakers noise
nickem7
No I know what "speaker noise" sounds like and it definitely wasnt sound from the speakers being used.
Speakers DO have a "quiet" sound
And they pretty much sound the same (the sound file and quiet speakers) but you heard the noise. As did i.
Help me!I can't here that!
there's no tone. the file is empty.
CZcams should focus on problems like Hz and unlimited FPS not Facebook-like interface and other irrelevant bullshit.
My nose is bleeding
Heard it
I can only hear it at max volume with headphone on my mac, if i go down 2 i can't hear it anymore, but it's definitely there, it's faint like a light hum - annoying though.
im 10 and i cant hear it :,,(
crappy headphones or ears
actually, you have to be 20 not to hear it anymore
con 29 años la escucho pero muy apenas
im 16 and i cant hear this is that bad????? fuck i need to stop going to concerts
Uh, I feel dizzy to hear that
I can hear alittle
I can't hear it, but it makes my head hurts nontheless
All these people saying it's obviously an empty file because their windows computers can't pick it up, for real? I can hear it, so obviously some people can hear better than a computer can. I am using a mac though, so I have the upper hand to begin with. I'm also 18. But, I'm also a musician who plays loud and doesn't use ear plugs, so I shouldn't hear this, it's pretty crazy, even I'm surprised.
It has nothing to do with the fact you have a mac.
Actually, MAC hardware could be way better than other computer's HW. For example, my PC doesn't play some of the 16k videos for sure, but some people do hear it. However, other videos play 17k with no problem. IDK what exactly is going on. I should get a software and try a legit high pitched tone :c
Patrik Rusinko it's called INTEL.
Matuu z INTEL your mom
Patrik Rusinko i challenge you to find a mac without an intel processor... that's the source of it's power, believe it or not
I can barely hear that. (17 years old)
Damn, I'm only 20, and can't hear a damn thing..
I'm ten and i can't hear it
14 and cant hear it
