Production Of Sound

Sound is a mechanical wave phenomenon and is normally associated with our sense of hearing. Sound is a property of vibrating objects.

  • Sound is produced by vibrating sources in a material medium. Medium can be any gas, liquid or solid.
  • The vibrating sources set the particles of a medium in vibration in such a way that sound travels outwards in the form of longitudinal waves.
  • Some of the energy of the vibrations are transmitted over a distance.

Examples of vibrating sources:

  • Musical instruments, like drums, guitar
  • Hitting a piece of iron with a hammer
  • Loudspeakers (Consists of a cone which vibrates under the effects of electricity and magnetism)
  • Explosion resulting from explosives.
