| Outline the components of the outer ear | Pinnae, external auditory meatus (ear canal) ending at the tympanic membrane (ear drum) |
| What is the function of the Pinnae? | The exterior visible flaps. Asymmetric shape helps to funnel sound into the ear canal. This also helps to disambiguate the locations of sound in space. |
| Outline the function of the external auditory meatus | Length (approximately 1 inch) provides some protection of the ear drum and inner ear from foreign objects. The shape and diameter help amplify sound (that are in a particular frequency region) through resonance. |
