Abstract
This paper reviews the underlying theory, the psychophysical test procedure, and the clinical applications of the aural-overload test. Clinical applications include (1) the delineation of persons susceptible to acoustic trauma, (2) the evaluation of postexposure damage to the auditory system, (3) assistance in site-of-lesion testing, and (4) the assessment of loudness recruitment. The relationship between aural-overload thresholds and speech-discrimination scores for normal and pathological ears is also discussed.
