How is a sound produced?

A sound is produced when an object vibrates, that is they move in a ‘to-and-fro’ motion.

For instance,

  • When we strike a tuning fork or a stretched rubber band, it vibrates and produces sound.
  • The human voice is produced because of the vibration of the vocal cords.
  • String instruments produce sound as their strings vibrate.
  • When a bird flaps its wings a sound is produced.
  • A flute produces sound because the air column of the flute vibrates as air passes through it.
