Capabilities of the Auditory System. What does the auditory system do and how well does it do it?. Hearing Sensitivity. The faintest sound that can be detected by the human ear is so weak that it moves the ear drum a distance that is equivalent to . Review the anatomy of ears. Correctly order the steps of inner ear response. Explain the brain mechanism for sound localization. Draw the central auditory pathway. Understand the common audiometric/special hearing tests. Assessment, Diagnosis, Treatment and Controversies. Defining Auditory Processing and APD. Auditory processing . may be described as the “efficiency and effectiveness by which the central nervous system (CNS) utilizes auditory information.” (ASHA 2005). Like light, sound travels in waves and like vision, in order to hear, we first need to receive the sensory input of the waves and then convert them into neural impulses sent to, and processed by, the brain.
