It is through the pinna that amplifies the sound and directs the sound to the ear canal. The ear of a human is divided into three parts. The pinna is located and part of the outer ear. Hearing does not take place here but rather this is the part where sound is collected and directed into the the internal passage called auditory canal. From this canal, sound travels or passes to the inner part and that is where the sound is processed.
