Explain why change of the pressure inside the ear is sensed when someone goes down a mountain?
Expert

When a person goes down a mountain the air pressure in the middle ear increases and it is essential to do some exercises, for example fake swallowing to force the pharyngeal orifice opening of the auditory tube to match the pressure again.
