Thresholds for triangular spectra with various subsets of AN model fibers based on average-rate information (a)–(c) or both rate and timing information (d)–(f). Each row corresponds to spectral envelopes with a given slope (G=100, 200, and 400 dB/oct from top to bottom). Human thresholds (Lyzenga and Horst, 1995) are shown as the solid line with no symbols. The selections of the CFs of AN model fibers for the small-population predictions are distinguished by different symbols. The line with circles is based on the model fiber with the highest sensitivity at each center frequency. (The selection of this best model fiber could change for different center frequencies.) The line with diamonds is based on a single AN model fiber with CF equal to 2106 Hz.
