Central in this phrase refers to within the brain. Simply put "it is the perception or complete analysis of auditory information sent to the brain".
Ineffective listening by itself should not automatically be associated with auditory dyslexia. It is possible that someone who doesn't listen is just bored or disinterested in the topics at hand. Another symptom that may be present in the dyslexic, is difficulty in sounding out words or even individual letters.
People with auditory neuropathy may get natural hearing, or hearing departure ranging from balmy to serious, they ever have impoverished speech-perception abilities, meaning they have problem agreement address understandably. Some patients with auditory neuropathy appear, based on history and initial behavioral testing, to fit into the category of "central auditory processing disorder". However, evaluation of such patients with physiological measures sensitive to auditory nerve disorders shows a more peripheral site consistent with auditory neuropathy. Sometimes people with auditory neuropathy are subsequently diagnosed with diseases such as charcot marie tooth disease and friedreich's ataxia. In these cases, auditory neuropathy may be a symptom of the more global effects these diseases rather than an isolated neuropathy of the ear-brain connection.
It's sometimes tempting to ask which type of short-term memory lasts longer: auditory memory or visual memory. Arguments for either exist but it's important to understand that in the end, it is the brain that determines which type of memory is stored.
The most prominent symptoms in auditory dyslexia are difficulty remembering letter sounds, identifying individual sounds in words and combining these sounds into words. Vowel sounds may particularly be troublesome, since each vowel can have several sounds.
There are actually three components to auditory processing. Each can be independently assessed by an Auditory Evoked Response (AER), Frequency Modulated Auditory Evoked Response (FMAER), and a P300. The AER assesses functional pathways as sound travels and is processed from the ear to the temporal cortex of the brain. The FMAER employs a specific auditory wavelength that "warbles" in pitch, creating a sound the brain recognizes as language. The P300 identifies the parameters of auditory attention in different parts of the brain and the time it takes to distinguish sounds, e.g. "cat" versus "cut." It is important to clearly identify the sources of the problem in auditory processing deficits. Different medications can affect each of the different auditory functions. In some cases, a medication can make a particular auditory function worse.
An audiologist can determine if there is a treatable problem and work with you, and in some cases with your doctor, to determine a proper course to correct the problem.
