You should know that the mechanichal waves are those waves which require a medium for propogation. Sound needs a medium (solid, liquid or gas) for their propogation and can't travel without a medium. Therefore sound wave is a mechanical wave.
Mechanical waves is characterised by the motion of the particles of the medium. Sound needs a material medium like air, water, steel, etc. for its propagation. Hence, sound waves are called mechanical waves.
