Binaural Listening and Interaural Noise Cross Correlation

The identification of different interaural correlations was examined over a range of reference correlations. Interaural correlations were produced by the method of Licklider and Dzendolet in which three independent noise sources were combined into two outputs. The change in interaural correlation (squared) required for 75% correct identification varied from about 0.4 for a reference correlation of 0.0 to about 0.04 for a reference correlation of 1.0.
