The sound must pass through the
auricle
before entering the ear canal.
As soon as the sound pass through the auricle, it goes through
external acoustic meatus,
then moves to the tympanic membrane.

reproduce vibrations coming from sound waves. After creating those vibration, it sends it through the 3 bones in the middle ear.
