Influence of interaural level difference (ILD) on interaural time difference (ITD). Data from monaural stimulation (A and B) and binaural stimulation (C). A: at equal levels of the clicks presented to the left and right ears (5 dB attenuation: L5, R5), the difference between right and left group delays (Δτgr) and phase delays (Δτph) were near 0 µs. B: when the level on the left side was decreased by 10 dB (L15), group delay increased, while the phase delay stayed constant. C: in the binaural situation with broadband noise as the stimulus, the positions of the extrema of the ITD curve for an ILD of 0 dB (—) were almost identical to the extrema of the ITD curve measured with an ILD of 10 dB ((...)). Events were obtained from an arbitrary setting of a TTL level trigger. Because Δτgr had changed but the ITD curve did not change, the phase delay, but not the group delay is important for representing ITD. Scale bars in A and B: 2.5 mV.
