Abstract

Changes in the magnitude of the acoustic reflex were used to estimate frequency resolution of the auditory system for five human subjects. Acoustic-reflex adaptation (decay) was produced by presenting a 2000-Hz sinusoid (adaptor) for 25 s. The spread of this adaptation to adjacent (test) frequencies was determined by evaluating the effect of the adaptor upon the magnitude of the acoustic reflex. The mean data from the experiment suggest that recovery from acoustic-reflex adaptation is more rapid for test frequencies below the adaptor frequency than for test frequencies above the adaptor. When these data are compared to tone-on-tone masking functions, qualitative similarities emerge between frequency selectivity observed psychophysically and those observed during measurement of acoustic-reflex activity.
