• Four case studies are presented to illustrate that low acoustic reflex thresholds may have value in assessment of central auditory processing disorders. Neurologic, electronystagmographic, EEG, speech pathologic, and/or psychological evaluations suggested CNS impairment. Tests for central auditory processing disturbance were positive. For three subjects, acoustic reflex responses were elicited at unusually low hearing threshold levels. A fourth subject showed lowering of acoustic reflex thresholds following bilateral electroshock treatment. These lowered thresholds were interpreted as hyperactive acoustic reflex responses representing a decreased central inhibition on peripheral auditory function. It is proposed that presence of hyperactive acoustic reflex responses may be associated with a concomitant central auditory processing disorder.
