Abstract : The resolution of frequency and amplitude is better at low signal-to-noise ratios with out-of-phase signals than with in-phase signals when the noise in which the signals are presented is the same at both ears. On the other hand, at high signal-to-noise ratios, the effects of the interaural phase of the signals are negligible. These findings are discussed in terms of the predictions of a modified version of Durlach's Equalization and Cancellation Model and the Webster-Jeffress Model of the binaural masking level difference.
