Why helium change voice

I don't need helium to talk in a high pitched voice because I learned how to do it. Dec 9, Neat, Karter! Do you like to do impressions or talk in funny ways? Oct 17, Shamar Jun 17, Jun 17, May 31, Alyanna Mar 3, What date did you make this article about Helium, i need it for my project in school. Mar 4, Aubrey muck Jan 4, Jan 5, Aubrey muck Dec 17, Dec 17, Hi, Aubrey muck! We're glad you liked this Wonder!

Visit again soon! Ed Dec 1, Dec 2, Harlee W. Dec 12, I love sucking air out of a bollon becouse its so funny when you do it makes your voice funny do you like making funny sounds. Wonderopolis Dec 12, That's funny, Harlee W.! Thanks for sharing with us!

Samantha Dec 1, If we breathed in a lot of helium mixed with air would it hurt us???????? Wonderopolis Dec 2, Emma Williams mrs. Mason's cla Nov 26, This is an awesome wonder Wonderopolis! On my 5th birthday, my dad sucked in helium and he said "hello everybody!

And on my step sisters birthday, we got to take six balloons home and then I sucked in the helium from the balloon. It almost felt like I was having laughing gas. Wonderopolis Nov 28, Joey Morris Nov 20, This is a question from my 5th grader named Miles Wonderopolis Nov 20, Kamren Nov 20, Hi, I was wondering about global warming. We are studying about water conservation in class and i was wondering about global warming like "How did it originally start, how its effecting us now and what we could do to help it not get any worse.

I was also wondering if we could stop global warming by changing our actions or by technology? Hope you get my question :] -Kamren. Ashton Nov 20, Anthony Nov 18, How come helium is so dangerous??????????????

Wonderopolis Nov 19, Gabe M Nov 18, Is there any other kind of air that can change your voice? Wonderopolis Nov 18, How can you die from to much helium????????????? Tamia Nov 18, M Nov 18, Thank you wonderopolis i wonted to know this! Simon C Nov 18, If I have a balloon I will usually do it, but not always because it can be harmful.

Simon C. Grace Nov 18, Sean M Nov 18, Why does helium make balloons float up then POP. Is there anything else that changes your voice by breathing it in. Michael Krieger Nov 18, Abby T Nov 18, I have never put a balloon in my mouth before unless its to blow it up. Have you ever sucked in the air before? If so does it tickle when you talk in a funny voice?

Eden Nov 18, I think that is cool. In some cartoons the person or animal they breath in helium and it makes them sound funny. Jeshaiah B. This story is interesting. I want to know why does helium only effect if it's around your vocal cords? Which means sound moves faster through helium than through air — nearly 3 times faster, in fact. So the sound waves bounce around faster in your vocal tract, which amplifies the higher frequencies in your voice. It's sort of like how speeding up your voice makes it sound higher.

But hold on a sec. These people aren't inhaling helium. They're sucking down sulfur hexafluoride, which is six times heavier than air. So sound waves move slower through it, which amplifies the lower frequencies in your voice. But here's the fascinating thing. The pitch of your voice hasn't changed when you inhale either gas, because your vocal cords move at the same rate no matter what gas you're breathing. So your fundamental frequency stays, well fundamental.

Regardless of whether you want to sound like Daffy Duck or James Earl Jones, keep in mind that inhaling anything but air can be dangerous. Especially when the gas is denser than air, because it will sink to the bottom of your lungs. Depending on its unique shape, your voice box naturally resonates or vibrates when certain wavelengths hit it. Those get boosted, and it sounds like this: Sulfur hexafluoride has the opposite effect on the voice as helium. Sign up for our weekly newsletter.

This is because nitrogen and oxygen molecules that make up the bulk of air are much heavier than helium atoms, so they don't oscillate back and forth nearly as quickly. That oscillating is what pushes the sound wave through the gas. In physics, the speed of a wave equals its frequency multiplied by its wavelength. So, if a sound wave travels faster through a vocal tract full of helium than it would through a vocal tract full of air, either its frequency or its wavelength must get a boost in a helium-filled cavity, too.

The wavelengths that resonate with the vocal tract depend only on its shape — i.
