FIG. 8.

Effects of a constant noise level on HRTF coding by HSR (A) and LSR fibers (B). Responses were obtained at multiple HRTF presentation levels in noise spectrum levels that were fixed at −10 and 10 dB SPL for HSR and LSR fibers, respectively. Plotting conventions are the same as those in Figure 3. Results are superimposed on discharge rates that were recorded in quiet, as previously shown in Figure 3 (red symbols).
