Because sound travells by air and if there is no air then sound cannot travel to your ears. A vacum is where there is no air e.g. space.

Do microphones work in the vacuum of space?

No, traditional microphones rely on air particles to transmit sound waves and would not work in the vacuum of space. In space, there is no medium for sound to travel through, so traditional microphones would not pick up any sound. Specialized equipment is needed to capture or transmit sound in the vacuum of space.


Can sound energy travel through the vacuum of space?

No sound can travel through space. Sound travels by vibrating adjacent molecules. The sound wave travels along these molecules until it dissipates with distance. In the vacuum of space, there are no molecules (this is not considering celestial bodies like planets or meteors because they are not a part of the vacuum), so sound cannot travel.


Can sound waves move through space?

No, sound waves require a medium (solid, liquid, or gas) to travel through, so they cannot move through the vacuum of space where there is no air or other material. In space, sound waves cannot propagate because there is no medium to carry the vibrations.
