The processing provided by the sense of hearing, auditory processing, allows us to interpret what we hear through our ears. The Sense of Hearing and Auditory Processing We can now say that human sensorial processing depends on six senses. More recently, the sense of balance provided by the vestibular organ located in the inner ear has been recognised as the sixth sense 7. Humans have been known to rely on the five senses of touch, smell, taste, vision and hearing to connect with the surrounding world. Sensorial processing is a generic term referring to the use of our senses to understand and connect to our surrounding environment 6. Human Sensorial Processing Depends on Six SensesĪuditory processing is a sensorial processing through the organ of hearing. More specifically, auditory processing is a set of skills required to analyse sound information during its transmission from the ears to the brain so that it can be interpreted and dealt with appropriately. There are also a number of children diagnosed with APD who have had no previous episodes of ear infection but may have other issues affecting their immune system and brain development.Īuditory processing ~ “what the brain does with what we hear”Īuditory processing is commonly defined as “what the brain does with what we hear” 5. Auditory Processing Disorder can also be Unrelated to Check here for Dr Leila Masson’s recommendations for how to prevent recurrent ear infections. Temporary diminished hearing commonly caused by ear infections deprives the brain of the appropriate auditory input required for the natural development of auditory processing skills.Īllergies that affect the upper respiratory tract (nose and throat) are common triggers of recurrent middle ear infections ³, 4 and consequent APD. Young children prone to “glue ear”, middle ear infection or otitis media are commonly diagnosed with an auditory processing disorder when starting school ². Prevention by maintaining a healthy body is by far the best remedy but even when an auditory processing disorder is already established, there are measures you can take to overcome the adverse effects and consequences for your child’s development.Īuditory processing disorder (APD) is a common finding amongst children with atypical development, behavioural and learning difficulties ¹. An auditory processing disorder may be diagnosed with specialised audiological assessment when the impaired skills are identified and individualised therapies recommended. Central Auditory Processing Disorder Can Lead toĪ breakdown in one or more of the skills required in the process may result in an auditory processing disorder. Interaction and integration of the signals coming from the right and left ears at the brainstem, midbrain and auditory cortex level need to be intact for appropriate processing to occur. The sense of hearing is a binaural system, as it relies on the input from our two ears. To understand a verbal stimulus one needs to be able to identify the sounds, discriminate the differences in tempo, pitch, loudness, sequence, localise and focus on the source of sound at the task and ignore others that are not important. Several analyses take place before a sound can be fully processed. Interpretation of speech signals requires a set of auditory skills that allow processing to occur. Speech is the most important auditory signal used for communication. Speech is an Auditory Signal to be Processed To interpret and respond to auditory information, the brain receives signals originated by sounds coming from the external world that first enter the ear canal, vibrating the eardrum, passing the middle ear, the cochlea and the auditory nerve through the brainstem all the way to the auditory cortex. Auditory Processing – the Function of HearingĪuditory Processing refers to the function of hearing, and ultimately the translation of sounds into meaning performed at the central parts of the brain named the auditory cortex. CAPD is not attributable to impairments in peripheral hearing or intellect. The more challenging the acoustic environment the harder it is to follow speech and verbal instructions.ĬAPD medical definition: Central Auditory Processing Disorder: also known as Auditory Processing Disorder is a disorder that is marked by a deficit in the way the brain receives, differentiates, analyses, and interprets auditory information such as speech. Children with Central Auditory Processing Disorder (CAPD) are easily distracted and cannot focus on an auditory task for very long.
