- Sound propagation requires a material medium (solid, liquid, or gas). - Sound travels at different speeds in different media (typically fastest in solids, slower in liquids, and slowest in gases). - Vacuum has negligible matter, so it cannot support the propagation of mechanical waves like sound.
