FIG. 7.

(Color online) Psychometric function parameter estimates for fitted functions in both NC and SC conditions as a function of simulated sound field (R0–R4). Each data point (open symbol) represents data from an individual subject in a given sound field. Filled symbols indicate parameter means for a given sound field. (A) Threshold parameters, α, with separate linear fits to the data for each sound field shown. (B) β parameter, which controls the slope of the fitted function. (C) Slope as defined by P(C)/dB over the linear portion of the fitted function around threshold. (D) Lapse parameters, λ.
