What is Outer ear?
Outer ear meaning Consists of the pinna or auricle (the visible projecting portion of the ear), the external acoustic meatus (the outside opening to the ear canal), and the external ear canal that leads to the ear drum. In sum, there is the pinna, the meatus and the canal. That's all. And the external ear has only to concentrate air vibrations on the ear drum and make the drum vibrate.
