Research, testing and recognition of Auditory Processing Disorder has resulted in a larger number of students  being diagnosed with Auditory Processing Disorder (APD) also sometimes called  Central Auditory Processing Disorder. Students with APD have great difficulty in processing and prioritizing the sounds they hear.  This in turn can result in a learning disability that often greatly impairs  the student’s ability to understand school lessons and to communicate their thoughts, ideas and understanding or the lack of understanding of things.

The following is a video that simulates the way a person with APD hears and interprets a teacher’s lesson in school.
