Hearing ability does not only refer to the sounds detected by the ear and transmitted to the brain for analysis, recognition and understanding and is only a small part of the auditory system as a whole Together. As such, hearing impairment refers to difficulty understanding in noisy environments, difficulty following complex instructions, or difficulty learning new words or languages. Individuals who can easily "hear" sounds or speech are not described as having hearing difficulties, and these difficulties are often attributed to other problems or disorders, which may result in the individual receiving incorrect treatment. The brain identifies and analyzes perceived pitch, loudness and loudness. duration and attempts to match them to learned or stored information, and thus we understand what is said or recognize meaningful sounds (Baran & Schminky, 1999). The definition of the American Speech-Language-Hearing Association recognizes that many neurocognitive functions are involved in the processing of auditory information, some specific to acoustic signals and others more general and not necessarily considered components of auditory processing (such as attention, memory and linguistic representation), unless they are used to process this auditory information (Baran & Schminky, 1999). Definition Central auditory processing disorder can be defined as impairment of one or more of the following perceptual phenomena (Baran & Schminky, 1999): sound localization (where the sound comes from, in relation to the listener); auditory discrimination (recognizing different sounds); temporal aspects (processing of acoustic signals over time, including ordering and integration of signals); perception with competing acoustic signals (perceiving speech... half the paper... or noise). However, the close relationship with attention deficit disorder means that the symptoms presented may be indicative of either, and that testing should be as thorough as possible to avoid misdiagnosis. Just as attention problems associate CAPD with ADD, language problems associate it with SLI. For this reason, symptoms of both disorders can present as “side effects” in children with CAPD. Katz, Stecker & Henderson (1992, cited in Baran & Schminky, 1999, p. 1) describe central auditory processing as “what we do with what we hear.” Since most people with CAPD have normal hearing ability, we are able to infer that it is within the neural transmission of messages that the disorder occurs. It can be treated or at least managed through individualized programs aimed at the various functions in which a child with CAPD may be deficient.
