The pinna works differently for low and high frequency sounds. The outer ear consists of the exterior structures of the ear, the auricle and external auditory canal. While some mammals have an ear structure similar to humans, other animals are less similar. Due to its anatomy, the pinna largely eliminates a small segment of the frequency spectrum; this band is called the pinna notch. The outer ear is made up of the pinna — also called the auricle (say: OR-ih-kul) — and the ear canal. The Ossicles. The ossicles, like the metal balls of Newton's cradle, serve to transmit energy, in our case carried by sound waves hitting the eardrum, through the middle ear and to a structure called the oval The human ear.
