Welcome
Auditory processing disorder (APD), also known as Central Auditory Processing Disorder (CAPD), refers to a condition that impacts the brain’s ability to filter and interpret sounds. People with APD have normal hearing capacity, but the mechanisms in the brain that process audio input are impaired, meaning they have difficulties receiving, organizing, and making sense of sound.
Children with APD are most likely to have difficulty in understanding speech especially in noisy environments, like a classroom or crowded shopping centre. They may also have trouble concentrating and reading when background noise is present. These problems may lead to difficulty in understanding and remembering instructions, speaking clearly and development of reading skills.
This test was adapted from the symptoms of auditory processing disorder (APD) as described by the British Society of Audiology. There is large comorbidity of APD with ADHD and hence it is helpful to screen for this in ADHD assessments.
