Why is there a sense of pressure change inside the ear when someone goes down a mountain?

When someone goes down a mountain the air pressure upon the middle ear enhance and it is essential to do some exercises like fake swallowing to force the opening of the pharyngeal orifice of the auditory tube to equalize the pressure again.
