Why is sound energy considered a type of kinetic energy?

Sound energy is a type of mechanical energy because it is the energy of molecules vibrating.

Vibration is a type of movement, so sound energy is kinetic mechanical energy. When two objects collide, they push on the air molecules around them. The air molecules vibrate and push on the air molecules next to them.

Sound is a longitudinal wave, i.e. it is transmitted by molecules moving in the same direction as wave propagation. The travelling wave can be considered kinetic energy, as the wave moves, and the standing wave potential, as it would only be dissipated once converted to a travelling wave.
