Why do you sound funny when you talk after inhaling some helium?

Helium is an inert gas that is lighter than air and can be inhaled briefly without risk of death. Sound is produced by vibration, the movement of air around our vocal chords. Because helium gas is lighter than the usual oxygen/nitrogen blend, it changes the resonant frequency of the human vocal tract, causing a faster vibration and a higher-pitched, cartoon-character sound.

Yes i found that instead of my farts sounding like a trumpet there were more like a flute.lol loux

i think i might know what you are talking about, i think the reason y u have weird noises is because u might just be burping. when u breathe in deeply u swalow some air that needs to be released. when u yawn do u have those noises too?

when you exhale as you hit you put more energy into it.  that is the sound it makes through the mouth guard.

because when you laugh your brain releases endorphins (a chemical in your brain) that make you feel good. same thing if you run alot, also called runners high. it just makes you feel happy, or better. which is also good if your depressed or something. just run and laugh alot. lol. :)

When the diaphragm becomes irritated it pulls down in sudden jerks resulting in sudden gasps of air.  When this air hits you vocal cords it results in the familiar hiccup sound.  The diaphragm can become irritated from eating too quickly or too much, an irritation in the stomach or the throat, or a feeling nervousness or excitement.

nitrous gas is called laughing gas but not because it makes you laugh... >surprise<\n\nit has a stinging odor and its vapors when inhaled make you cough up... this probably is the "laughing"... it can also irritate your eye...\n\nwhen you cough, i don't think you can talk at all... but i think, if ever you can, it still depends on the quality of voice you have... \n\n\n:-) chemical engineering student...

The biggest reason is how much gas is mixed in. But no - you do not make helium in there! Haha, though it does sound like Donald Duck whether y0u talk from your butt or inhale helium from a balloon.  The gas you make in the large intestine is mostly methane. (It's combustible - famous "blue darts" - try it)  Helium is not combustible - it's a noble gas.

Hold your nose while you talk, it makes you sounds stopped up...

Take a quick sip of it and that air comes out when you speak.\n\nDon't try to do it a bunch of times in a row though. There's no oxygen in helium so i passed out once trying to do it for too long.

"Hic!" You've just hiccuped for what seems like the tenth time since you finished your big dinner. Wonder where these funny noises are coming from? The part to blame is your diaphragm (say: die-uh-fram). This is a dome-shaped muscle at the bottom of your chest, and all hiccups start here.\n\nThe diaphragm almost always works perfectly. It pulls down when you inhale to help pull air into the lungs, and it pushes up when you exhale to help push air out of the lungs. But sometimes the diaphragm becomes irritated, and when this happens, it pushes up in a jerky way that makes your breath come out differently from how it normally does. When this irregular breath hits your voice box, you're left with a big hiccup.\n\nSome things that irritate the diaphragm are eating too quickly or too much, an irritation in the stomach or the throat, or feeling nervous or excited. Almost all cases of the hiccups last only a few minutes. Some cases of the hiccups can last for days or weeks, but this is very unusual, and it's usually a sign of another medical problem.\n\nYou've probably heard lots of suggestions for how to get rid of hiccups, and maybe you've even tried a few. Holding your breath and counting to 10 is one way some people can get rid of their hiccups; other people say that drinking from the "wrong" side of a glass of water is the way to become hiccup-free. Putting sugar under your tongue might work, too. And maybe the most famous treatment - having someone jump out and scare you when you're not expecting it - helps some people wave good-bye to their hiccups.

Helium alters your vocal cords (temporarily, as I'm sure you discovered), causing the pitch of your voice to arrive.\n\nWhile it can be a lot of fun, repeated exposure to your larnyx isn't good for it.

Its when theres an air pocket and we rub it and we push that air pocket...so it makes a farting noise.\n\nIt happened to my ex a few times long time ago, but I knew it was normal so it didnt phase me.\n\nAll men know its a normal thing, so dont wig out...its a beautiful thang.

When we talk air passes out from our lungs through our vocal chords and is caused to vibrate and you hear the words. When you mix helium with air the resulting mix is less dense so as you breathe out the timbre of your voice is altered. The spped of sound in a less dense helium/air mix is higher than in just air. You are increasing the speed of sound of your voice when breathing out this less dense mixture and this increase in speed will affect the frequencies that make up your 'voice'.\nIf the frequencies are affected the timbre is affected too. A more dense gas may have a very wierd affect.\nStrictly speaking although most people say it is the pitch that changes, it is the actually the 'timbre' which is changed, as your vocal chords produce the same shapes and therefore the same pitch

i think it has something to do with a "flight or fight" syndrome. like when you get startled. except when you are nervous, you know there is no need to run and you really have no need to fight, so therefore, you laugh. some people stutter or get flustered, you laugh. nothing wrong with it, just maybe say excuse me, im a little nervous. if you are feeling pressure, explain that the person is making you uncomfortable and could they please back off.

Helium is a lighter gas than Air and causes the vocal chords to vibrate faster due to the thin gas, thereby producing the "squeeky" sound.

On June 3, the bodies of two college students were found in a giant helium balloon in Florida. The week before, a 10-year-old in New Jersey collapsed at a birthday party after sucking helium from a balloon. Is helium really that dangerous?\n\nIt can be. Breathing in pure helium deprives the body of oxygen, as if you were holding your breath. If you couldn't breathe at all, you'd start to die in minutes—as soon as your body exhausted the supply of oxygen stored in the blood. But helium speeds up this process: When the gas fills your lungs, it creates a diffusion gradient that washes out the oxygen. In other words, each breath of helium you take sucks more oxygen out of your system. After inhaling helium, the body's oxygen level can plummet to a hazardous level in a matter of seconds.\n\nYou don't have to worry about fatal asphyxiation if you're sucking from a helium balloon at a party. At worst you'll keep going until you get lightheaded and pass out—at which point you'll stop inhaling helium and your body's oxygen levels will return to normal. Of more concern is the possibility that you'll hurt yourself when you fall down. (The boy in New Jersey bumped his head and needed three stitches.) It's far more dangerous to suck helium out of a pressurized tank: If the gas comes in too quickly, your lungs might burst and hemorrhage.\n\nOf course you're putting yourself in grave danger anytime you climb inside a giant helium balloon. The college kids in Florida weren't the first to attempt this stunt. In 2002, a case report from a Japanese medical journal described a similar episode: A drunken adolescent poked his head into an advertising balloon and asphyxiated. Several authors have also reported cases of suicide by helium inhalation. \n\nDeath by helium still seems to be quite rare. U.S. Poison Control Centers reported only two fatalities between 2000 and 2004. There's still an outcry from concerned parents whenever helium inhalation makes its way into popular culture. Federal Express had to pull a commercial that depicted the munchkins from The Wizard of Oz sucking balloons to keep their voices at a high pitch. Geoffrey, the Toys "R" Us giraffe, got a slap on the hoof for doing the same. \n\nAt the same time, doctors use a mixture of helium and oxygen (called "heliox") to help patients with upper-respiratory blockages. The treatment works because the helium is a very light gas, and it's easier to push it through an obstructed airway. (We get funny voices when we inhale helium because the lighter gas changes the resonant frequencies of our vocal tract.*)
