For everyone who doesn’t hear this: In 99% it’s because of your speakers (mobile phone for example).
When you feel something but doesn’t hear anything, then it’s because of your ears
It sounds just like the washing machine XD
There’s something wrong with your washing machine my guy.
sounds more like a washing machine at 2x speed
Distant copter sound
But uncomfortable
@@ericryu1086 sounds more like my really fast washing machine
Fascinating funfact about this Frequency:
This is the heartbeat maximum from a Etruscan shrew: 1200-1500 beats per minute = 20-25 Hz.
The weight of this mammal is 1.8 grams.
It can increase its own bodytemperature at a rate of 0.83°C per minute, which is among the highest values recorded in mammals.
They have 2-6 cubs per litter.
Cubs are born naked and blind, weighing only 0.2 grams.
Have a nice day.
😂
Nerd 🤓
heater rodents
AWESOME comment thank you for the knowledge!
@@minimyers1170 😬
Put it on 0.25x speed, pause it and unpause it. It makes the weirdest noise
tylerthenormal what the fuck
scary sound like someone sneezing lol
2x speed
Sounds like someone passing gas.
Someone’s farting or making fart noises with their armpits or a wet fart lol
That's how it feels and sounds when there's an earthquake.
I ran out of my room. I'm not even lying.
thats the same i was gonna say
also when a tiger roars
Bro xDDDD
If you pause and play the video it makes a really loud popping sound.
Thorn on a bad music system, yeah.
It has nothing to do with that.
Wow mine does it. It’s probably from the high frequency being cut off so quick
If your on an iPad or phone and you turn up the volume it also makes a sound lol
@@Yakubi I'm sorry for being that "person" but low not high :P
I just came here for the vibes.
ME TOO
you passed the vibe check
I think he means the vibrations not vibes that word is not 3 years old like the comment.
Me and the boys vining to 20 hertz
I cant hear anything but i feel my ears pulsing
おまんてぃす
@Cringeyness Expressway you evil little one
If you have no problems in hearing, maybe your device can't reach 20hz or it is weak at those margins...
Yes
why the holy does it sound weird with earphones when i breath
Didn't think I was still capable of hearing that frequency 👍
Your capable of feeling i mean vibrating
If you heard a washing machine noise u didnt hear the frequency xd
@@elzu3781 ha 😂
Well as we age, our hearing loss tends to be most prevalent in the higher frequencies. The older you get, the less high of a frequency you can hear.
Luckily, that means we can enjoy low bass like this our whole lives 🤣.
Your system can't play it lol
nice helicopter
It`s massage for my ears cause nice bass)))
more like washing machine
This one makes me totally convinced the house around me is moving lol
your ears themselves are vibrating at this freq
When i breath, it sounds like driving on a gravel road
Woah I can hear that. Giving me a headache tho
same
It's hard to explain but basically since it's very low frequency you can't really hear the noise because you weren't made to, but the noise is here and it's very loud
The Lovely Steenee Same
some dude behind a computer I can hear it and it tickles lol
samw
It sounds like my neighbors washing machine.
These videos are good for testing speakers and amps.
Then you did not hear it
try playing in 0.25 this is weird
pause and unpause while in 0.25
Dr. Chops wtf
Wtf
Turn playback speed to 0.25 and pause and unpause the video
lol It's like the bass drop is never going to hit.
Beginning of a horror movie lol!
this sounds very relaxing to me
Thats actually unusual, because data showstopper sounds below 21 hertz make people more anxious and paranoid. Since your body can sense it, but not hear it.
Breathing with this + earbuds = FUN
Tengo tarea de biología, pero me puse a buscar 'qué es sonido' y ahora no puedo parar.
¿Cómo fue la tarea de biología?
cuando dice ajusta tu volumen quiere decir que debo subirle o bajarle
@@joaquin-flores depende lo que quieras o necesites, solo te alerta
Try to talk at the same time with high volume 😆
H i
B b u e n o
No
I can literally feel my headphones shaking
massage with noise
I can feel my whole body shaking omegakekw
wtf liszt play rhapsody p
@@fudeusilva huh? Play which Rhapsody? And my hardest Rhapsody isn’t even my hardest piece if that’s what you want me to do
@@AntorasStudio no. 12 please
my favorite
0.25 : weird sound
0.5 : alien like sounds
0.75 : lightsaber or something
1 : normal relaxing sound
1.25 : sound exe has stopped
1.5 : alien like sounds 2
1.75 : spaceship sounds
2 : also relaxing
Try breathing when u have headphones on it's trippy
0.25x: When UFO comes to your home
2.0x: When your computer fans not really working
Normal: NANANANNAANANNANANANBAZZZNZBZBZNANANNANANZBZBZZZ
Man sound is funny, I can hear the oscillation of the sounds pressure pushing through the air but I can also feel it running through my body. If anyone lives in California, you can agree it's like a small earthquake tremor kind feel to it
ugh, i hear this when its very silent when im in bed but a little bit smoother
you can get intense anxiety and fear from hearing infrasound (sounds below 20hz) which can deprive you of sleep, which is why you should turn the lights on and try to think of other things or bring someone in bed with you, and I mean it as in literally have someone near you in bed while you are asleep just so you will not get scared, this is a real thing, search it up.
morethen alover I've never seen or heard of that before but it sounds super interesting, oddly enough the really low frequencies calm me down and help me relax
@@badmeow2312 What the fuck is wrong with me then? These really low sounds are so relaxing to me its the fastest way to fall asleep....
@@nikolasslead6582 that's because you're probably a fuckin sociopath
pulsatile tinnitus?
I noticed when I listen to it with my eyes closed, my eyelids would twitch uncontrollably then it calmed down after the video stopped
this feels like a massage in my ear. saved.
Damn, some decent ASMR from this too
If you use skull candy ear buds with the rubber plugs and use the NCH tone generator app you can go much lower. I can hear it all the way down to 5hz then below that can only feel the pressure lol
Same! This makes my neck pop.
I hear absolutely nothing, guys.😂
did you used headphones?
I hear it
This pleases my ears.
Yeah i can definitely hear it... It's faint (I mean it's super low, lol, makes sense, it's on the edge of the limits of human hearing), but i definitely can... I don't understand why some musicians and sound engineers say you can only hear that frequency after being freshly born, lmao... And i'm 30 years old with hearing damage (tinnitus, partial deafness in some specific frequencies).
Truth be told, your treble-hearing is what deteriorates as you get older, the lower ranges of hearing, are the sturdiest part of human hearing due to the anatomy of the human ear, and thus, the least likely to deteriorate as you age.
29 years old and I can hear it pretty clear actually. I laughed when I was told to "try" and listen to this. I blow my ears out with metal all day and have since I was 14.
Maybe people should update their research because I'm doubting this to be true amongst most people.
Got a transducer on the chair. Wife is gonna love this beat lol
They called this the Ghost Sound, Cause at 20Hz your brain can actually get a Paranormal feel from the low Hz Vibrations. But as soon as you turn it off, It slowly goes away.
What...?
2x speed sounds like you're inside of some diesel truck
When i close CZcams while the Video, my Headphones make a sound like an small explosion
I love this test tone. When I start smelling my subs then ill play this test tone to cool them off while this 20hrz test tone.
Thanks
A continuous test tone will absolutely not cool off your speakers.
@@jasonm3835 yes its possible, when the venting holes ( ex. A horn loaded or bassreflex) ar too small and the speaker cant cool down whit higher frequencies because the moving of the membrane push and suck the air to fast for an exchange. So if its because of this effect, the speaker will be realy bad desingned/calculated and i would take instant a hammer and destroy it
With earphones / headphones :- yes
Without :- nope 🙅
So what does it means???
People here claiming it to be loud whereas for me it is almost muted though at the highest volume it sounds like 10% of it
At the highest volume it sounds like 0% of it for me. 😂
Pausing and playing makes a popping noise in my earbuds
8 Bit Nation yeah because they jump to the original position.
Kind of a fact:If u twice the playback speed it would actually double the freq(well somewhat,halving it also does the reverse(10hz).....)
*This is what it sounds like if you do DMT and put your ear to the engine of a HotWheels car.*
YOOO THIS IS TRUE
It's so deep that if you set the video to play at x0.25 speed it pitches up.
I hear it for sure. Makes my ears feel so funny.
If you set it at 0.5x speed it sounds like one of those telephones in the 90's.
I swear I hear this while I’m tripping on acid, it always sounds like an idling diesel nearby. Very interesting.
POP POP POP POP everytime i pause it xD
The funny thing is the first time I saw this video my speakers couldn't even play it.
Damn! I didnt think I would be able to hear this with headphones... but it is loud and clear!
Other signals in the playlist were giving me 1.5V peak-to-peak. This is giving me just 300 mV. Is this intentionally kept low volume ?
this feels like it will wear out my subwoofer if played too long
6 years on, idk about your sub but my A10s got really hot after putting a few of these through them. think imma stop now lol
Actually wouldn't it be easy on your subwoofer, since it only has to move 20 times per second?
@@dartheater7348 depends on how much power and cone excursion, if it was a shitty sub and required a lot of power to play loud, and that causes a lot of excursion, it would be very bad
@@jesuschrist711 lol back then i had a Polk PSW505 that my beats fried. Now I have an SVS SB-16 Ultra that makes my house shake.
Got two IEMs to compare, one with a slight boost in the sub-bass so I'm interested to see how they differ. This one at least, the tone is crushing even at low volume hahaha. Ouch.
my free earpods from 2016 can produce sounds up to 20hz, but my 40$ headphones which i bought like a month ago can only produce up to 40hz
I played this and it shook the whole damn house
If I listen to this on my headphones with my fan on, it makes a weird combination of sound, like a helicopter sound.
Yeahhhh 😅😅😅😂😂😂
i mean....i can see my sub moving and feel my whole room shaking...but i dont really hear anything hahhahaha
Thank you, this is extremely useful rn. Tuning a bass to blue whale spectrum. Thanks!
When you change the volume in makes a clicking noise
yeah i noticed that too what device and headphones were you using?
ProEraSwank I don’t remember but this feels like 2 weeks ago. I need to stop procrastinating
my klipsch kg 5.5 shaking my house to bits with this
My ears are vibrating love it
Who hears this in the wintertime when the cars go by?
That makes sense, I believe I hear that. The sound is very interesting and makes my whole head hum.
Even all my neighbours houses play it lool
Use some headphones and and set your volume to maximum, it feels like your headphones are vibrating as crazy!
Are you suppose to use headphones when listening because i cant hear or feel anything with my phone speaker on high
I can feel it there but it can't hear it, it's like wind. These headphones are rated for 5 hz
Holy shit. playing it at x2 speed with a woofer is scary
My daughter start humming in the room when I played it
I was vibing to this at max volume, then an ad played. Ouch
I use this daily to cool down my subs thank you!!!
i can feel my eyes being vibrated.
Do it 0.25x speed and it's an alarm
just the artwork on the walls shaking, sub is nearly silent, NHT-CS10
Que som gostoso pra dormir 😅
So calming. Feels like om
om
@@ramicyt actually it is aum. We write it om. But this is wrong.
It is. This is the frequency of a cat's purr.
@@seetclear8947 cat's Purr means? 🙂
@@cosmiccommandovlogs7904 the noise a cat makes, the humming noise. It's called purring.
Feels nice in my ears
Why is it so satisfying when you pause it
Pausing it and unpausing it at 0.25x gave me a hand spasm lol
Had a little hard time hearing that but I find that 18000 hertz is easier to hear.
its shaking my brain
I have Cheap speakers, when i pause then i hear a small "pop!" and when i wear headphones and do that, its much more quiet.
Put the video at 0.75X sounds like 1000CC cafe racer
Bruh trying this on a 15in sub has it GOING I swear
My tinnitus loved this one ☝️
Wh-1000xm2 sony headphones ,
this the lowest it supports its very very impressive .
The low sound is good‼️
Play at 0.75 speed as soon as possible your speakers damage 😂
I heard the sound
With max volume
Up to my ear
20hz is the lowest audible frequency to humans
it doesn't sound as low as i thought it would be, i feel like i can hear tones lower
ALV CUANDO ESCUCHE ESTO PENSE QUE ESTABA TEMBLANDO ALV!!!!
PD:LUEGO LO PUSE EN UNA FIESTA Y SE ESPANTARON XDDD
x2
yo sentí mareos
clean diesel sound😂
This isn't just 20Hz, there are other highert frequencies too, I played next to my cat and she heard it, meaning this is above 48Hz
nice using these with the hesh 3's wich is a skull candy headphone brand feels nice on my ears
im playing 30,40 and 50hz all at the same time and its making a really weird effect o.0
Try playing 440Hz and 480Hz at the same time.... Might sound familiar.
We don't have these specific tones on our channel, but if you have an app that can play two frequencies at once you can try this. :]
Helicopters be like.
i feel like my body is shaking but it's not. weird lmao
It also makes noise when you change ur volume
Bro I thought I was gonna break my headphones and now my ear vibrating
put it at 1.75 you can actually hear the musical note ( Eb0 )
i can feel my headphones vibrating
It means that it vibrate 20 times in 1 second????
