Interaural correlation discrimination thresholds were obtained for auditory pulse trains. Pulse trains of random polarity or of random pulse occurrence were delivered to the two ears. The interaural correlation is defined by the pulse‐by‐pulse agreement between the ears. Coding by pulse occurrence and coding by pulse polarity are about equally effective, except for larger thresholds for polarity at low pulse frequencies. Thresholds for the discrimination of changes in positive interaural correlations are smaller than corresponding thresholds for negative correlations. Interaural correlation discrimination thresholds for pulse trains are comparable to those obtained with wide‐band continuous noise.
