FIG. 6.

Simulated masker-and signal templates. This figure shows the binaural excitation pattern of the simulated masker-and signal templates as function of gammatone filter center frequency and interaural time difference for both masker conditions for gerbils (A) and humans (B). Upper row of each panel depicts the masker template; dotted circles indicate side ridges that occur for humans at higher frequencies (for more information, see text). Rows 2–7 of each panel depict the signal template for each corresponding loudspeaker separation. The upper color bar depicts the excitation for the masker template. The two lower color bars depict the signal induced changes of excitation for the simulated gerbil (left) and human (right). Both excitation and change of excitation are given in arbitrary model units. For further explanations of the differences in the binaural excitation pattern, see text.
