(A) The mean ILD cue (◻, +pin) computed across the six intact animals varies as a function of azimuth along the horizontal plane and frequency. Error bars indicated ±1 standard error of the mean (SEM). The mean ILDs are shown for six frequencies from 5 to 30 kHz. The mean ILD cue for three animals after removal of the pinna is also shown (●, −pin). Removal of the pinna reduced the ILDs for frequencies >10 kHz. (B) Rate of change of the ILD cue (i.e., ILD slope) with changes in source azimuth along the horizontal plane between ±30°. The ILD slope was obtained from the mean ILD cues computed across the six animals (panel A). Error bars plot ±1 SEM.
