The Voice is of High pitch

Explanation:

  1. We know that Speed of Sound is Directly proportional to the Resonant Frequency of Cord.
  2. Now, the helium get filled into the voice box of a person.

We know that,  

  • The Speed of Sound in Helium = 3\times (Sound in the air).  
  • This helps us to know that, in this case the Resonant frequency is Higher which makes it clear that the voice will be of high pitch.

Thus the voice in Helium filled voice box is high pitched.

Explanation:

  • In the voice box, the frequency of sound created by vocal chord vibration is intensified by resonance.
  • The resonant frequency in the voice box is directly proportional to the intensity of the sound present.
  • That Helium has low density than air, sound velocity in Helium is greater than that of air.
  • Higher sound velocity in Helium indicates that the sound's resonant frequency in voice box filled with helium will be greater than that of air. Thus the voice in Helium filled voice box is high pitched.
