The way sound travels

Pinna - Ear canal - Eardrum - Hammer - Anvil - Stirrup - Cochlea (creates nerve impulse) - Auditory nerve --> cerebrum 

When climbing a mountain/taking flight

Air pressure on the outside is very low, on the inside relatively high. You'll have to swallow some water in order to 'pop' your ears.

Air pressure pushes on eardrum

Eustachian tube connects to your nasal cavity/throat.
