Investigation of the threshold duration function of the acoustic reflex in 5 males and 5 females with normal hearing and in 3 males with cochlear hearing impairment reveals that the threshold duration function for normal hearing subjects encompasses a greater intensity range than the psychophysically assessed auditory threshold temporal integration function. Sex differences are attributed to subclinical noise induced cochlear pathology in the male subjects with subsequent truncation of the reflex threshold duration function. The function is also truncated in the 3 subjects with cochlear hearing loss. Implications are discussed for control of stimulus duration in clinical reflex measurement.
