The phonemes allow the brain to distinguish words from other sounds. After entering the cortex, the brain is able to recognise various features of sound, called phonemes.
When sound enters the ears to go to the brain, the signal goes through the brainstem, then moves to both sides of the brain via the central auditory system. Greater attention to APD can help support the case for more scientific research and lead to solutions for mitigating or resolving APD effects. While the cause (or causes) of APD are still being explored, the growing interest is spurring more conversations around this learning disorder.
In many cases, children with APD often have siblings with learning disabilities. Others believe it could be caused by vaccinations, while some experts think APD could be hereditary. The cause may be due to environmental concerns, such as lead exposure or poisoning. Another shares that children with APD often have language development disruptions or delays. One is that many children with APD also had multiple ear infections earlier in life. Its cause remains unknown, but there are a few theories. History of Auditory Processing DisordersĪPD was first identified in 1954, when it was originally called Auditory Perceptual Disorder. The problem lies in how the person understands the sounds they hear. The person may have normal hearing capabilities. With auditory processing disorder (APD), the brain is unable to process sound correctly. It allows the brain to save, organise, and understand information from what we hear. Proper auditory processing is critical to learning and communication. It then analyses those sounds to give them meaning.
To process audio, the brain must identify the sounds and where they’re coming from. It helps us make sense of what we hear, whether it's noise or speech. What Is Auditory Processing Disorder?Īuditory processing is defined as a neurological communication between the ears and the brain.
Auditory processing deficit how to#
Here’s what the science says about sound processing and APD and how to respond if your child may have APD. Auditory Processing Disorder-is it just another label? Or is there scientific research that has raised our awareness of the deficit? In light of the growing body of evidence, APD can pose a risk to a child’s learning and development if left unchecked.
