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? Landon A. Thanks wonderopolis now I know why people talk different and why do you think people's voice is different?
Emma K. Hi wonderopolis! I was wondering how long your voice is in that squeaky tone when you breathe in helium? I really liked the wonder of the day!
I was wondering I know you said breathing a little bit of helium is no danger but could it still be a danger? Bro Yo Nov 18, How can inhaling a lot of helium be SO dangerous? And if you breathe in a lot of helium how long do you think your voice will be high pitched?????????????? The human voice is made up of many different tones mixed together.
At the same time, it makes the lower tones resonate less in the vocal tract. The two effects combine to create a Chipmunk-like, flat sound. When sound waves speed up but their frequency stays the same, each wave stretches out. This moving series of compressions is a sound wave, and the distance between them is known as the wavelength. All gas samples have the same number of molecules per unit volume at a given pressure and temperature, whether the gas is helium or nitrogen the primary constituent of air.
But not all gas molecules have the same mass. Nitrogen and thus air has a mass roughly seven times greater than that of helium. Nitrogen is thus denser than helium and sound waves travel through it more slowly than they do in helium. At 20 degrees Celsius, for example, sound travels at meters a second through helium, but only at meters a second through air. Like the vibration of a drum or a violin string, the vibration frequency of the vocal cords is independent of the type of gas that surrounds them.
Whereas the velocity of the sound waves is faster in helium and the wavelength greater , the frequency remains unchanged because it is determined by the vibrating vocal cords. If your vocal folds wiggle back and forth times each second, they produce puffs with a frequency of beats per second Hz. Additional motions of the vocal folds, such as collisions with each other, generate additional frequencies that are multiples of that fundamental frequency: "harmonics" at Hz, Hz, Hz and so on.
All these frequencies travel together through the vocal tract — the tubelike cavity leading from the voice box up through the throat and mouth to the outside world. Depending on its shape, this tract resonates with certain harmonics generated by your vocal folds, meaning it vibrates in time with them. In doing so, the vocal tract amplifies those resonant harmonic frequencies, making them louder. So, the harmonics created by your particular vocal folds paired with the shape of your particular vocal tract produce a unique collection of resonant frequencies that, taken together, give your voice its distinctive sound quality, or timbre.
