Note: Dash indicates that no valid roex fit was obtained. For normal-hearing (NH), hearing-impaired (HI), and corresponding age-matched, simulated-loss (AM-SIM) listeners, the following parameters are shown: upper and lower slope parameters pl and pu; slope-parameter ratio pu/pl; filter dynamic range r; efficiency term k; equivalent rectangular bandwidth (ERB); and 3-dB-down filter bandwidths (BW-3dB).
