, also known as Central Auditory Processing Disorder (or CAPD), is a complex problem that affects the way the brain processes auditory information.


APD is known to affect thousands of school-aged children and adults. Approximately 2-7% of school aged children have some type of auditory processing disorder (2-4 in every average size classroom) and according to the National Institute of Health, in individuals with learning difficulties the prevalence has been found to range from 43-75%.


Individuals with APD have difficulty processing the information they hear in the same way as other listeners because their ears and brain don’t fully coordinate. APD adversely affects the way the brain recognizes and interprets sounds, most notably the sounds composing speech.


APD is a type of hearing loss not located in the sensory organs in your ears, but in the part of your brain that processes & interprets what you hear. This can contribute to significant speech, language, and learning problems.


Individuals with APD often do not recognize subtle differences between sounds in words, even when the sounds are loud and clear enough to be heard. These kinds of problems typically occur in background noise, which is a natural & common listening environment. Therefore, people with APD will have difficulty understanding any speech signal presented under less than optimal conditions (i.e., noise, accented speech, fast talkers, etc).
