Strictly speaking, with pressure there's only "push", with "pull" being
actually a push in the opposite direction:
(1) Pressure differential exerts a "pushing" force from high-pressure to
low-pressure region
(2) Pushing force accelerates medium in the gradient zone, speeding it
up until the pressure differential is compensated
(3) Inertia of the accelerated medium causes "overcompensation" of the
pressure differential
(4) Pressure differential is now reversed -> back to (1), now with
opposite direction
This is all that happens locally; at a larger scale, this will cause the
pressure differential to propagate through the medium as a wave.
