Any vibration that disturbs air molecule, is capable of making sound. The source of vibration pushes and pull air molecules, causing acoustic signals known as sounds. The sound heard are based on three major factors; that is: The source of vibration that forms the sound waves. The medium which is known as the wave carrier. The receiver that detect the sound. The source of vibration occilates and brings surrounding air into motion through a medium (such as air) and if the receiver is present the sound can be perceived. Sound is a mechanical disturbance that travels through an elastic or viscous medium at a speed depending on the characteristics or features of the medium. While air tubulates, the mass and momentum of the sound are the "sound generators". The diagram below shows how the sound are generated. Diagram showing how sounds are generated.
