1.Why does helium change your voice?

Most kids would agree: Sucking a lungful of helium out of a balloon makes your voice sound hilarious. But contrary to popular belief, the switch from air to helium gas doesn’t actually increase the…

2.Why does helium change your voice?

Your voice doesn’t actually change pitch with a lungful of helium: your vocal chords still vibrate at the same frequency. Rather, what changes is the natural frequency of your throat, so it resonates more strongly with the higher harmonics than the lower ones.

3.Why does helium change your voice?

The helium actually affects the sound quality of your voice (its tone or timbre) by allowing sound to travel faster and thus change the resonances of your vocal tract by making it more responsive to high- frequency sounds. Helium is the second most abundant element in the known universe (hydrogen is the most abundant).

4.Why does helium change your voice?

The speed of sound in helium is almost three times faster than in air and this changes the resonant frequency of your throat so that high frequencies sound louder than low ones. If you inhale a gas that is denser than air, such as sulphur hexafluoride, the sound travels at just 39 per cent of its speed in air and your voice sounds deeper.

5.Why does helium change your voice?

If you’ve ever inhaled from a helium balloon at a birthday party or watched this scene from My Best Friend’s Wedding, you know helium does weird things to your voice. It makes it sound high and squeaky, like a rodent from Alvin and the Chipmunks. But, surprisingly, inhaling helium doesn’t actually change the pitch of your voice.

6.Why does helium change your voice?

When you inhale helium, you’re changing the type of gas molecules in your vocal tract and increasing the speed of the sound of your voice. Some people think that helium changes the pitch of your…

7.Why does helium change your voice?

To generalize, we find that helium does not affect your vocal cords, and helium drastically changes the timbre of your voice without having any significant effect on its pitch. It happens that helium is less dense than air, and so, the speed of sound is much higher in helium.

8.Why does helium change your voice?

Helium is much lighter than air. The speed of a sound wave through helium will then be much higher. So by inhaling helium and using it as the source of the perceived sound, you are simply increasing the speed or frequency of your voice.

9.Why does helium change your voice?

Since helium makes our voice sound funny, many people think it is because it increases the pitch of our voice. But this is not true. Our vocal cords vibrate at the same frequency, but our voice changes with helium because the gas affects our tone or sound quality by allowing sound to travel very fast the speed of our voice increases.
