Production of Sound

Bertleja, Academic Content Writer for Physics at Edumarz


  • Sound is produced when objects vibrate.


  • Vibrations are rapid backward and forward motion of objects.


  • Vibrations propagate through a medium such as air to our ears, where they are interpreted as sound by the brain.


  • Three things vibrate when a sound is produced:


  1. The source object

  2. Molecules in the medium

  3. Eardrum of the listener


When an object vibrates, it       produces sound. The sound waves travel through a medium which causes the molecules in the medium to vibrate. When the sound wave reaches the outer ear, the eardrum  vibrates.


  • Examples of vibrating sources of sound:


  1. When we pluck any stringed instrument, it vibrates and produces sound.

  2. When a flute is blown, the air column vibrates within it and produces sound.

  3. When a tightly stretched elastic band is plucked, it vibrates and produces sound.

  4. The rapid wingbeats of humming bees create vibrations that are heard as  buzzes.
