Why are sound waves called mechanical waves?

Sound waves are called mechanical waves because they need a material medium to travel.

Sound waves force the medium particles to vibrate. Hence, these waves are known as mechanical waves. Sound waves propagate through a medium because of the interaction of the particles present in that medium.

Sound waves are called mechanical waves because they are produced by the motion of particle of a medium. Hence sound waves are called mechanical waves.

Sound waves are called mechanical waves because sound needs a material medium for its propagation.
