You had me up to that point.
Air pressure and friction are two different things. Sound is air pressure waves that because of the nature of waves, have very little friction. Evidence of this is how far they can travel.
Air pressure waves acting on an ear drum move it because of the pressure changes at the drum's surface. The air is not actually grasping the ear drum using friction.
