Abstract
Investigation of the temporal integration of the acoustic reflex [human] may be complicated by the operating characteristics of the instrumentation used to record the reflex. Several experiments were conducted to determine the operating characteristics of 2 impedance measuring systems (Madsen, model ZO-70 and Zwislocki Bridge (Grason Stadler, model 3), and to measure selected characteristics of the acoustic reflex, including threshold, reflex intensity-growth functions and temporal integration functions at threshold for several stimulus frequencies. A smaller impedance change may be identified with a Madsen ZO-70 due primarily to the higher S/N (signal-to-noise) ratio in that instrument; differences in temporal integration functions obtained between the 2 instruments were partially accounted for by differences in the operating characteristics of the 2 measuring systems; the slope of the growth-intensity function decreased as signal duration decreased; and the slope of the temporal integration function increased as the frequency of the eliciting stimulus increased.
