Question

why are sound waves called mechanical waves

Answer 1

Electromagnetic waves do not require a medium in order to transport their energy. ... Because mechanical wavesrely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles. That is, mechanical waves cannot travel through a vacuum.

Answer 2

☆$\red {HELLO\:DEAR}$☆

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.
