Why does your voice change when you inhale helium?
How you sound: characteristics of air+throat+mouth+nasal cavities +tongue+lips.
- First of all: Helium is less dense than air; that’s why helium balloons rise.
- As a result of its lower density, sound travels 2½ times faster in helium than in air.
- The cords vibrate when air passes; higher lower pitches correspond to cords length and thickness.
- Faster speed means higher pitch, so as helium travels through your airway across the vocal cords, the pitch is much higher than usual.
- The more dense, or heavier, the gas, the slower the sound wave will travel.
- 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.
- If you inhaled a heavier gas, your voice would sound deeper.
FalseYour vocal cords are over worked when you inhale helium.
- Your vocal chords are vibrating at the same speed as when you are using air.
- The frequency of the sound heard by others is increased due to the wave traveling through helium much faster than through air.
- Men have a lower pitch than women
- Until puberty, the larynx of men is similar in size to that of females. From this point,means thyroid cartilage increases and they get the Addams apple.
- Helium has the lowest boiling and melting points of all the elements and as such exists only as a gas, except under extreme circumstances.
- Helium is the second most abundant element in the universe and accounts for approximately 24% of the elemental gas in our galaxy.
- Every time you inhale pure helium, you are not inhaling oxygen.
- Whatever you do, never inhale helium from a high pressure tank! (You dont want helium bubbles ready to give you a stroke)
