Sound is energy. Sound is power.

How does sound travel?
Sound travels when something vibrates and air particles hit the other particles and makes sound waves that take the sound to your ear.
How do we hear sounds?
When the particles vibrates then it passes the vibrations on to the other particles and the sound wave goes into your ear and goes into your three bones and it goes into your cochlea and then it sends a message to your brain.

Because there is no air in space. Sound needs to travel in air.
