TABLE III.

Slope values for the input/output functions of several auditory filters, for center frequencies from 0.25 to 6.0 kHz. In each case, the slope was calculated over the input range 30–80 dB SPL. (See the text for details.)

Probe frequency (kHz)	0.25	0.50	1.0	2.0	3.0	4.0	6.0
Roex (Table II of Glasberg and Moore, 2000)	0.73	0.70	0.39	0.56	…	0.57	…
Roex (Table IV of Glasberg and Moore, 2000)	0.51	0.50	0.45	0.44	0.37	0.39	0.36
Cascade cGC filter (six-coefficients) (Patterson et al., 2003)	0.62	0.50	0.42	0.37	0.36	0.35	0.34
Cascade cGC filter (seven-coefficients) (Patterson et al., 2003)	0.69	0.57	0.48	0.40	0.36	0.33	0.29
Parallel roex filter	0.71	0.65	0.58	0.49	0.44	0.40	0.35
