Stimulus design can minimize monaural cues to isolate pure binaural phase processing

Evidence

In order to generate IPM, the overall magnitude of the carrier IPD was held constant throughout the stimulus, but the ear at which the signal was leading in phase was periodically modulated between right and left. Each IPM was applied instantaneously at a minimum in the modulation cycle in order to minimize the (monaural) salience of the instantaneous phase transition (see Fig. 1 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2949

Categorization

• DEFINE: IPM (interaural phase modulation) is defined here as periodic switching of which ear leads, holding the IPD magnitude constant.
