Hearing and Auditory Processing Basics
... The Auditory System The auditory system is divided into four parts: 1. Outer ear (OE) – consists of the pinna and external auditory canal (meatus) which is responsible for hair cell secretion of cerumen (wax). The OE is responsible for localization and funnelling sound into the ear. Earwax protects ...
