For each experiment, the carrier frequency (fc), the modulation frequency of the A SAM tone (fmod A) and the modulation frequency difference between A and B SAM tones (Δfmod) are indicated. Δfmod conditions that are printed in bold typeface show conditions in which stream segregation was can be explained on the basis of spectral cues (Dolležal et al., 2012a) estimated from a model calculating excitation pattern differences between the A and the B SAM tones in the inner ear. Spectral cues provided by Δfmod conditions that are printed in regular typeface are unlikely to be sufficient for stream segregation.
