Which direction do air particles move when a sound wave travels from east to west?

We know that sound waves can be transverse or longitudinal. Furthermore, sound waves are caused by the vibrations or oscillations of the sound wave particles in any given medium. The medium determines the nature of sound wave propagation.

In a longitudinal wave, the particles of the medium move in a direction parallel to the direction of energy transport. Therefore, when the sound wave travels from east to west, the air particles also move parallel to the same direction. Hence the air particles also move in east-west direction
