the particle will move left and right at 10hz because sound wave is a longitudinal wave and the mean position will be the same.

A wave is a phenomena in which there is a transfer of energy, but no permanent displacement of matter. Think water waves - each water particle bobs up and down - but energy passes through them.

With sound, a longitudial wave, the particles go back and forth horizontally at a certain frequency (as you know).
