why does helium, when you suck it in, make your voice go squeaky?

Answer 1

Your vocal cords do NOT vibrate faster when you breath in helium, they vibrate at the exact same rate.

However, the change IS due to the fact that helium is lighter. Think of it this way: your "voice box" is a resonance chamber for sound... as your vocal cords vibrate the wave form emerges with a particular frequency which is emitted. When you change the media in which the vibration occurs, the resonance chamber properties are different and so the resonance occurs at a different frequency (picking up on harmonics off the main frequency at which the vocal cords are vibrating). This different frequency is then emitted, accounting for the change in pitch.

Answer 2

it is a bad element TO DO. whilst it says on the cylinder it is risky... they actually do advise it. Helium gas used in balloons is a by utilising-fabricated from organic helium used in the electronics industry. whilst it is of little need to them it is bought off as balloon gas. It now includes all of the nasty stuff used in the production of semi conductors (arsenic, lead, mercury different heavy metals and oils) then you definately inhale this and over the years the acquire in the physique and might reason illness and dis-function of the physique's organs. As for the squeaky voice the helium travels out of the lungs swifter than air because it is lighter. the swifter the air the better the frequency of the voice. PLEASE do not DO IT

Answer 3

Its a much lighter gas so your vocal cords can move quicker and so vibrate quicker and make a higher pitch. However don't breath too much of it or you will get suffocated like two students did.
