Molecule vibrations.
Explanation:
Sound waves travel and hit the atoms/molecules of the medium, which triggers chain vibrations. That is why we can hear sound through mediums but not in a vacuum. Also, sound travels through solids the fastest, as the particles are really close together, but the slowest in a gas, because the particles are far apart, and thus making the sound wave travel longer to trigger vibrations.
