Interaural noise correlation inversely drives the magnitude of binaural release from masking.
Evidence
Robinson and Jeffress (1963) demonstrated this by varying the amount of correlation of the noise between two ears. They found a systematic increase in the release from masking as the correlation of the noise between the ears progressively decreased. Noise highly correlated between the ears (e.g., identical noises to the two ears) led to the largest masking effects, whereas uncorrelated noise between the ears afforded the largest release from masking. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1562
