This may manifest as poor auditory comprehension, delayed language development, poor expressive and receptive language or high distractibility, though many other symptoms are also noticed. Without this ability, relationships, learning and development are all challenged.Īuditory processing disorder is often present from early childhood, leading to a number of difficulties as the child becomes older and messages become complex and are given more quickly. How we make use of auditory information is a complex and interdependent network of hearing, listening, and the brain’s processing of information to produce appropriate responses. It is impossible to isolate the components of this system or to consider that any sensory system only affects its specific domain. Ideally, auditory processing should enable people to decode auditory signals as they are delivered, integrate auditory information with other environmental cues, organise this in a meaningful way, screen incoming auditory information to sort the relevant from the irrelevant, and lastly to associate sounds with written language. Depending on the type of processing dysfunction, different problems will emerge. This is precisely what happens with auditory processing. Where one type of interference may cause distraction, another may cause frustration, misunderstanding and / or confusion. The line may cut in and out, there may be a small time delay, or there may be a lot of background noise. If there is any kind of interference on the line, the reception of the given message will be compromised. The ear and the brain communicate with each other, not unlike two people having a conversation on a mobile phone. ![]() It is, in effect, the wiring between hearing and understanding. Not all children who fall into the categories mentioned develop APD, but many children with the disorder have experienced at least one of these issues.Īuditory processing is the system that transfers and decodes what we hear into what we understand. These children may have learned to be discouraged by listening, while others block out aggressive sound if they are hypersensitive to certain frequencies. ![]() Some children have early experiences with sound that involve either a lack of auditory stimulation or a noisy environment. These include a complicated birth, childhood ear infections or colds, glue ear, allergies, or a slow speech development. In addition, there are some developmental issues that have been shown to have a relationship to APD. Many children with APD have a family history of auditory difficulties or partial deafness. ![]() All the ensuing problems are collectively known as Auditory Processing Disorders (APD). ![]() When parts of this complex system break down or don’t operate efficiently, listening is compromised. It also requires a good attention span, a well-functioning memory, and sensitivity to the many subtleties of sound. Effective auditory processing involves a relatively high speed of information transfer. Auditory processing describes the way the brain assigns significance and meaning to the sounds in the environment. Where hearing is a function of the ear, auditory processing – listening – is a function of the brain. People who have normal hearing actually hear far more than they perceive. This makes it difficult for the child to process verbal instructions or even to filter out background noise in the classroom. Auditory Processsing Disorder (APD) is a neurological defect that affects how the brain processes spoken language.
