What is a hearing disorder?
A speech disorder
is an impairment of the articulation of speech sounds, fluency and/or voice. Speech sound disorders include problems with articulation (making sounds) and phonology (sound patterns), and apraxia (motor speech disorder caused by difficulty with the idea, planning and execution of the muscle movements needed for speech), dysarthria (motor speech disorder caused by weakness in any of the muscles required for speech/respiration).
A language disorder is impaired comprehension and/or use of spoken, written and/or other symbol systems. The disorder may involve (1) the form of language (phonology, morphology, syntax), (2) the content of language (semantics), and/or (3) the function of language in communication (pragmatics) in any combination.
A hearing disorder
is the result of impaired auditory sensitivity of the physiological auditory system. A hearing disorder may limit the development, comprehension, production, and/or maintenance of speech and/or language. Hearing disorders are classified according to difficulties in detection, recognition, discrimination, comprehension, and perception of auditory information. Individuals with hearing impairment may be described as deaf or hard of hearing.
