You can make your voice sound like you used helium without actually breathing it in by constricting your airways while you talk, forcing the air to go through a smaller opening at a fast speed.
Fun fact: Making yourself puke without gagging(like ramming a foreign object down your throat) is actually really easy. If you can fake burp, you should be able to do it. Just eat/drink something light(whatever you think will be easiest coming back up), and suck in air the same way you do for a fake burp. Now instead of pushing that air back out(making the actual burp noise) just keep sucking air down more and more and more until..... well until you puke. I've never met someone who couldn't actually pull this off. Most people just don't realize they're stopping because of the discomfort that comes with puking, and everything in their being is so used to going "STOP OR YOU'RE GONNA PUKE!" If you simply ignore that, and keep sucking air down the "wrong pipe" whatever you ate recently is gonna come back up and make a huge mess. One more bonus fact: Suppressing gag reflex is actually pretty easy too. Just squeeze your thumbs(for me and I believe most people the left hand works best, my girlfriend squeezes both) and keep breathing through your nose. Idk much about why this works so well. I think it's just that motion happens to relieve and tense the muscles running up your arm to the side of your neck. When I say "squeeze your thumbs" I mean just lay your thumb into your palm, wrap all 4 other fingers around, and just keep tightening and relaxing the grip on the thumb(I learned the last one when I was a worthless druggy and wanted to swallow 60 large capsules in one gulp)
Basically helium is less dense than normal air at sea level, and your voice is resonating through less dense air speeding up the sound. If you breathe in Sulphur hexafluoride, it will do the opposite as it is more dense than normal air.
This is, because in a tuning fork, it's the metal that vibrates at the given frequency and the air only transmits the vibration. Our voice works differently. The resonance of the throat is a significant part of it. So when the speed of sound is altered, this resonance is altered, too. Hence the higher voice.
Helium atoms are lighter, so their brownian speed is higher at room temperature. The harmonics of your voicebox of the same wavelength are now higher frequency because the speed of sound is faster.
in music/voice terms, we call that a “formant.” :) i’m a voice actor, and depending on how i position my tongue and larynx, i can have a “squeakier” voice or a deeper sounding voice at the same pitch. it’s all about how you form your body’s resonators to get different effects!
Once upon a time, when i was 13, a 16 year old boy died at a Chuck e Cheese's from inhaling helium from several balloons without stopping to take enough of a breath. Your body doesn't notice a lack of oxygen as suffocation, it notices a build up of CO²
Frequency will always remain constant for a particular source anywhere in the universe however the speed and wavelength may vary from media variations.
As a side note, the tuning fork is a mechanical resonator that's weakly coupled to the atmosphere, all the vibration happens in the metal. I expect a flute to get a higher pitch.
So to post edit my voice to sound like I was using helium, I shouldn't be stepping up the frequency of the whole recording but instead putting it through a spectrum equalizer to increase the volume of the higher pitched components of the speech.
😂i always thought that the helium did something physical and temporary to your voice box. I feel really foolish but relieved that it doesn't work the way I thought. 😅
A tuning fork isn't going to change it's frequency in a vacuum chamber it's a dense metal object that was modeled after vocal cords. But vocal cords are apart of an entire system of things working together. So a vacuum chamber probably won't do anything to vocal cords since you'd probably need to be in a pressure suit. And you're body gets certain things pressurized internally for things to run proper so lower air density could be the reason or it could be the fact that helium is still not something your brain is used to inhaling that and it could be helium poisoning.
Near the end you said it makes them sound louder, should be higher there too. Anyway, Garage 54 made an excellent video about this topic, with helium and also with a heavier gas they made engines sound both higher and lower pitched.
In essence though it does make it higher. When you think of the 'frequency' of the tuning fork, you're thinking of its resonant frequency, not the frequencies produced from the impact (which can be all over the shop). In the same way, when you think of the frequency of your voice, you're thinking of the resonant frequencies, which are altered by replacing helium with air; in the same way as if you replaced a steel tuning fork with a copper one.
Isnt the resonant frequency frequency dependent and not wavelength dependent? I thought the frequency changes, because the vocal cords can vibrate more freely in Helium than in air, because helium has less mass. I think if you tried the same experiment with a very thin string in helium vs in air, the string would vibrate slightly faster in helium than in air.
444hz is an odd tuning. Generally, a tuning fork would be 440hz for A4 at standard concert pitch. Maybe this is one of those "healing" tuning forks that use certain frequencies to heal people.
I thought that the changes in voice after Helium inhalation could be explained just considering that for the sound traveling inside the throat through Helium the higher speed could be the same as actually having a smaller resonance cavity. Please, would someone with more knowledge and a better understanding explain if I'm getting this wrong? Thanks in advance
Our voice is not a percussive instrument, but a wind one. As such, it produces sound by vibrating the gas which flows inside. (Usually air, but possibly Helium) So this experiment doesn't apply as evidence of what you're trying to prove.
I always thought it was bc of the medium change from helium to air, that should shift frequencies? Helium ha almost tripple the speed of sound, so the waves would be squeezed together when they hit the slower air?
The truth is the resonance HAS NOTHING TO DO WITH OUR VOICES SHIFT. Helium is ligther and smaller molecules AND obviously MUCH LESS DENSE that AIR MIX, so for a given force, HELIUM EXERTS much less resistance so the the amplitud of wichever wave is bigger, bounces back faster (less resistsnce) and thus creates a higher frequency in its back and forth movement.
Wouldn't it also matter that with a tuning fork the metal is what resonates (Which causes vibration of the air), and with a voice it's the air that resonates? How would this test work if you were to blow over the top of a bottle?
I was expecting the ActionLabs guy to inhale some helium at some point in the proceedings. I am hugely disappointed at his lack of demonstration, unless of course he is allergic to the inert gas. If this is the case, then I do forgive him. 🙄
Oh god, he's starting to morph into Vsauce with these outros
I think I was subconsciously affected by his most recent zoom in...
Or his he?
at least he doesn't give me existential crisis everytime i watch one of his video
The man's about to eat helium instead of inhale it.
@@Kj16V I heard the Vsauce music when I read that lol
My man was having more fun than was legally allowed.
lol
weirdest possible ending
I just watched till the end because I have suspicion that his gonna inhale helium, I'm sad 😔
Lol
:D
I feel like homeboy at the end was on more than helium, dude's way too excited about that balloon xD
Funny thing is that he sounds like being perpetually on helium lol
Your sense of humor has come a Long way and beautifully evolved...

@@nignamedmutt7270 do you know what I appreciate your knowledge.👍
This is the answer to a question I never knew I have.
Bro casually hypnotized us 💀
That zoom at the end

And it makes Adam savage sound hilarious yes
We had to use that website you used to show the change in wavelength for physics class at the beginning of the year.
That went in deeep at the end
The outro is what clinched the thumbs-up for me, boss
It doesn’t make it higher but it makes a illusion of thinking its more high-pitched

The resonance of the throat is a significant part of it. So when the speed of sound is altered, this resonance is altered, too. Hence the higher voice.
Yes. But your vocal chords are probably responsible for the fundamental frequency
@@DANGJOS yes, that's right. But as you can easily try for yourself, they are not fixed to one frequency like a tuning fork is.
@@andrebartels1690 I would imagine not. Probably higher harmonics on top of it
very succinct brother! I also love the terrifying ending
The ending was super weird, but the lesson in this was super cool to learn.
We all have to wonder why you did not inhale the helium.
Missed opportunity to speak the script having inhaled helium.
It really has to do more with the harmonic series and which overtones are more/less present (timbre).
help, I'm dying, too funny
Helium atoms are lighter, so their brownian speed is higher at room temperature. The harmonics of your voicebox of the same wavelength are now higher frequency because the speed of sound is faster.
Not sure he's saying the same thing in the video
A helium scream at the end would have completed it 😂😂
Pure greatness

My headphones volume was maxed out... I almost lost my hearing... It's still ringing
Thank you for your videos!
Frequency will always remain constant for a particular source anywhere in the universe however the speed and wavelength may vary from media variations.
u are turning into vsauce
Bro became vsauce in the end
Yea. The picture at the end shows exactly how excited a man is at the sight of balloons.
It does feel like my voice has a microphone when I suck down some helium
Who knew that 444hz induces headaches? Cause now I do!
It made me (mentally) melt, it was like heaven for my ears
As a side note, the tuning fork is a mechanical resonator that's weakly coupled to the atmosphere, all the vibration happens in the metal. I expect a flute to get a higher pitch.
I agree that the flute would be a higher pitch. In fact, I'm pretty sure someone actually tried it with a musical instrument.
Because your vocal chords are not made of Aluminum, Genius!
Correct. So many get this wrong. It changes the timbre, not the fundamental frequency.
Modal tones apply not only to tuning fork but to the gas itself. And those have different density in normal condition thus different rigidity.
You can hear the pitch rise as he fills the tank with helium. So cool
I'm gonna see that ending when I close my eyes at night.
this is something I've always wondered about and could never find a proper explanation (I even looked really hard once) 🎉 thank you so much!
Frequency is source dependent.
And speed=freq.x lambda
The higher frequencies are more pronounced, so it sounds higher, so it is higher.
Well, you can tell by the way I use my walk I breathe helium, and high I talk.
Love your videos, man! Glad to see you educating in a fun and entertaining way.
I was just wondering about this the other day because I knew the frequency shouldn’t changed based on the medium the sound wave travels through.
I thought I was about to get rick rolled 😅
So if we use Sulfur Hexafluoride would they actually get louder since it is that much deeper and lower?
Yes
Although I think the reason has to do with the greater mass of the molecules (basically the same as saying the gas is denser)
So to post edit my voice to sound like I was using helium, I shouldn't be stepping up the frequency of the whole recording but instead putting it through a spectrum equalizer to increase the volume of the higher pitched components of the speech.
Always wondered about this! And why the usual explanation didn't really make sense... thanks!
looks like someone watched some vsauce
Love this channel. Would be great to teach kids in science class.
😂i always thought that the helium did something physical and temporary to your voice box. I feel really foolish but relieved that it doesn't work the way I thought. 😅
so did i! i had always heard it's because it tightens/shrinks your vocal cords.
Crazy I just did this today, now I have a wicked headache
That ending gave vsauce vibes
I like how it sounds with nitrous oxide even more! sounds like evil Disney villain!

I don't think that guy is holding a helium balloon 😂
“stop wasting helium” like 6 videos later 😂😂

It was about helium but the ending felt more like nitrous😳
In the end He makes your voice Higher
IS THAT A MOODY BLUES STAND FROM JJBA?!!!?
If smth gets faster like w this w Helium, the Amplitude may change, but the freq gets higher & the wave therefore must be shorter. Vice versa->4slower

Are you saying that the ultrasonic frequencies that we supposedly emit go down into a perceptable frequency and we hear that?
6 year old me: Impossible

If you blew over the top of a bottle, the frequency will definitely be higher with helium.
Cool shirt! Where is it from?
Is more like squeaky or sharper than higher imo.
So basically helium is like putting on HD glasses but for your vocalbox?
So does this mean if you put a recording of your voice in a box with helium it wouldn't sound like it was affected?
I was expecting the ActionLabs guy to inhale some helium at some point in the proceedings. I am hugely disappointed at his lack of demonstration, unless of course he is allergic to the inert gas. If this is the case, then I do forgive him. 🙄
Why don't speakers sound lower underwater then, which is obv much denser than air?
Thank you for the zoom at the end 😐
God damn wizard.
Aaaw our cat reacted to that note
Is a tuning fork really analogous to the vocal chord though?
I don't understand... So the helium doesn't change your voice but just makes the higher frequency of your voice louder?
I always thought it affect the lungs so the voice change 😵💫😵💫
Why bro why it's 2 am now I can't sleep again
Frequency is the property of the source not the medium 👍
So the baby voice WAS ALWAYS THERE YOU JUST COULDNT HEAR IT
The only way I’ll enjoy physics
👹
Try playing a flute in helium! 😄
This is very interesting!!!
Is this the krusty krab?
