A sound wave needs a medium to travel. A sound wave travels in the form of a longitudinal wave and it requires a material medium for its propagation. Sound always originates from some vibrating body. These vibrations are produced by tuning forks, drums, bells, the strings of a guitar, etc.

Sound needs medium to travel because it needs medium to propagate it by generating vibrations.
Like in air, it needs vibration of air particles to propagate.
So it can't travel by vacuum.
