This investigation determined the recovery of the acoustically evoked potential in man as a function of intersignal interval (ISI) when each member of a click-pair was presented to opposite ears and evoked potentials were recorded from areas overlying both cerebral hemispheres. Acoustic clicks (0.1 msec in duration) were presented alternately at a 50-dB sensation level to the right and left ears of four normal-hearing subjects during each of four experimental and 12 treatment conditions. The click-pairs were alternated with single clicks whose responses provided criterion measures against which recovery was judged. Measures of central tendency and variability were obtained for all subjects during each treatment condition and under all combinations of signal presentations and recording locations.
