Expert Answer:

Sound waves are longitudinal waves. Sound waves propagate in the medium through series of copmressions and rarefractions.
 
Particles vibrate in the same direction of sound wave propagation. 
 
Sound waves are produced by a vibrating body.
 
There is a medium that carries the disturbance from one location to another. Typically, this medium is air.The medium is simply a series of interconnected and interacting particles.
The sound wave is transported from one location to another by means of particle-to-particle interaction. If the sound wave is moving through air, then as one air particle is displaced from its equilibrium position, it exerts a push or pull on its nearest neighbors, causing them to be displaced from their equilibrium position. This particle interaction continues throughout the entire medium, with each particle interacting and causing a disturbance of its nearest neighbors.
Since a sound wave is a disturbance that is transported through a medium via the mechanism of particle-to-particle interaction, a sound wave is characterized as a mechanical waves.
