Auditory Processing Disorder

Auditory processing is defined as what the brain does with what it hears. Although the ear is responsible for picking up sound and directing it towards our auditory system, it is auditory processing that allows us to differentiate and interpret these signals. Auditory processing is responsible for sound localization and lateralization, auditory discrimination including auditory decoding with a degraded signal, auditory pattern recognition, temporal aspects of audition and auditory performance in the presence of background noise or a competing signal

Central Auditory Processing Disorder

Central Auditory Processing Disorder (CAPD) is the term originally used to describe a condition in which a person has difficulty hearing despite showing normal hearing sensitivity through audiometric testing. The term “central” was used to describe the location of the disorder, which is in the brain. Central auditory processing is not the same as peripheral hearing. Peripheral hearing instead occurs in the ear - either in the inner ear (cochlea), middle ear (inside the space within the eardrum) or outer ear (ear canal).
