FIG. 3.

Spectrograms for left- and right-ear sparse-noise stimulus with different ITDs applied to different frequency regions. The target-band region between 1 and 4 kHz has a 1-ms ITD with the right ear leading, the complementary outside-target-band frequency range has a 1-ms ITD with the left ear leading. Thus, identical temporal features occur earlier in the right ear in the 1–4-kHz target band, and earlier in the left ear in the outside-target band. For illustrative clarity, the chosen ITDs are larger than those used in the experiment. Sound levels are again color coded (blue = −20 dB, red = +40 dB).
