1. A sound is a form of a wave.
2. When a wave travels the particle of the medium vibrates.
3. Due to the vibration of the particle, the sound is produced.
4. The speed order of sound waves is decreasing in the medium as Solid$>$Liquid$>$Gases$>$Vacuum
5. In a vacuum the are no particles to vibrate.
6. Since there is no vibration, there will be no sound.
