We studied the 2IFC detectability of a 500 Hz tone masked by computer-generated maskers under the NOS Π interaural condition, and under two masker conditions. In the first masker condition the maskers in the two intervals of a trial were independent of each other, and in the second masker condition the maskers were identical, although maskers varied from trial to trial. Thresholds were higher for the independent-noise condition than for the identical noise condition. These results have implications for the Theory of Binaural Interaction Based on Auditory Nerve Data.
