The effect of interaural phase on frequency discrimination with broad- and narrow-band maskers.
With both broad-band and narrow-band noise maskers there is a small range of signal-to-noise ratios where, with the maskers in-phase and signals 180 degrees out-of-phase at the ears, detection performance grows with increasing signal-to-noise ratio but frequency discrimination performance does not. The observation may have significant consequences for our understanding of the way in which frequency is coded at low signal-to-noise ratios.
