What it the function of your pinna? the pinna is a part of your ear. but seriously, what is the function of a pinna?

Hello! The function of the Pinna is to be a kind of funnel that assists in directing sound further into the ear. Without this funnel the sound waves would take more direct routes to the auditory canal. This would be difficult and wasteful as much of the sound would be lost making it harder to understand the sounds.  Hope this helps!
