Abstract
A monaural complex tone is synthesized from 12 harmonically related pure tones played in phase. In each of 12 segments, 1 of the tones (the target) is played out of phase so that the sequence of targets is increasing or decreasing in frequency. If the target is at least 30.degree. out of phase, the targets are perceptually segregated. This tone-segregation by phase raises doubts concerning several current theories of pitch perception. The phenomenon is conjectured to be caused by the human ear''s nonlinear compressive transfer characteristic or by a temporal analysis of the stimulus.
