Auditory Processing Disorder (APD) is not easily defined. This is because there are many different views and definitions of Auditory Processing Disorder. One view many Audiologists and Speech Pathologists use is the ASHA (2005) definition. This particular definition highlights the poor function of the central auditory nervous system (CANS). Therefore, a number of tests are required to assess for APD. Each test assess different functions.
Children with Auditory Processing Disorder usually have normal hearing. But appear to have a hearing loss. One of the signs of Auditory Processing Disorder is mishearing what people say. Another is, not appearing to hear people from a distance. Other difficulties include concentrating in noise and following conversation in noise. Children with APD can also have difficulty following long instructions.
So, why should we test for APD? Because, children with APD have difficulty hearing in noisy a place such as a classrooms. So this can make learning to read and write difficult.
The results of APD tests are used to develop a management plan for the child. This includes advice on how to help the child in the classroom. As well as, providing information on auditory training activities.
It should also be known that; APD can coexist with other disorders such as ADHD and Language and Learning disorders. But APD is not caused by these. ASHA (2005)
