What is the defrence between animal sharp and round ears?
ddd [48]

It's also known as the pinna or auricle. The outer ear's shape helps to collect sound and direct it inside the head toward the middle and inner ears. Along the way, the shape of the ear helps to amplify the sound — or increase its volume — and determine where it's coming from.
