  • Why Does Inhaling Helium Turn Human Voice Funny?
    When the sound travels at a speed of 1007 m s in your vocal tract, the voice timbre is the one that changes and not the frequency or pitch of your voice When you speak with helium in your vocal tract, the sound is propagated from one medium (helium filled vocal tract) to another (air)
  • Why does inhaling helium make ones voice sound strange?
    It is the lesser density of the helium--which serves as the medium for the sound waves--flowing through the larynx that produces this differing quality in the voice
  • Why Helium Makes Your Voice High Pitched (And Makes You Feel . . .
    Because helium is lighter than air, sound waves travel through it faster This changes the resonance of your voice, amplifying high-frequency sounds and suppressing low-frequency sounds
  • Why does helium change your voice? - BBC Science Focus Magazine
    Helium and air are both gases with very similar compressibility so the much lower density of helium causes sound waves to propagate about 2 7 times faster Your voice doesn't actually change pitch with a lungful of helium: your vocal chords still vibrate at the same frequency
  • Why Does Helium Change Our Voice? - Smore Science
    When you speak with helium in your lungs, the sound waves produced by your vocal cords travel through the helium much faster than they would through regular air This increase in speed causes your voice to sound higher and squeakier than usual There is a bit of myth-busting that is needed too
  • Why Breathing Helium Changes the Sound Of Your Voice - Today I Found Out
    When the sound waves leave your mouth and enter the atmosphere, the medium is just normal air (helium is in your mouth and lungs) The atmosphere air should slow down the sound waves back to “normal” speed, and the frequency we observe should be back to normal
  • Why Does Helium Change the Sound of Your Voice? - Wonderopolis
    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
