(A) Spatial distribution of envelope ITDs for two animals (R016 and R004) for locations in the frontal hemisphere. Positive ITDs indicate that the signal leads to the left ear. Color bar and countour lines indicate the ITD in microseconds. (B) The envelope ITDs in three animals (R001, R002, and R004) as a function of azimuth along the horizontal plane in two conditions: intact (filled symbols, +pin) and after removal of the pinna (open symbols, −pin). Removal of the pinna reduced the ITDs at all azimuthal locations.
