Figure 2: Correlation of CHLDP with CHLPT as determined using three distinct sets of optimization formula parameters. In panel A, ear-specific parameters were utilized. In panel B, a generic, frequency-specific (1 kHz) optimization formula was used [1]. In panel C, a generic, frequency-nonspecific optimization formula provided parameter values [1]. The dashed line in each panel indicates y=x. Reprinted with permission [2].
