What is central auditory processing?
When the ears detect sound, the auditory stimulus travels through the structures of the ears, or the peripheral auditory system, to the central auditory nervous system that extends from the brain stem to the temporal lobes of the cerebral cortex. The auditory stimulus travels along the neural pathways where it is “processed,” allowing the listener to determine the direction from which the sound comes, identify the type of sound, separate the sound from background noise, and interpret the sound. The listener builds upon what is heard by storing, retrieving, or clarifying the auditory information to make it functionally useful. What is a disorder of auditory processing? APD is an impaired ability to attend to, discriminate, remember, recognize, or comprehend information presented auditorily in individuals who typically exhibit normal intelligence and normal hearing (Keith, 1995). This definition has been expanded to include the effects that peripheral hearing loss may contribute to audit
