Table 1. Psychometric functions before and after optimization.

Level adjustment	SRT, dB SNR	Slope, %/dB	Predicted test-specific slope, %/dB
Before	−11.50 ± 2.81	14.60 ± 3.59	10.2
After	−11.50 ± 0	14.60 ± 3.59	14.8

Data are presented as mean ± standard deviation.

SRT = speech reception threshold, SNR = signal-to-noise ratio.
