FIG. 4.
Scatterplots illustrating individual speech reception in steady state noise (SNR-50) as a function of SRD threshold at 20 dB (a), SMTF slope (b), and SMTF x-intercept (c) in CI listeners stratified by age group. Line of best fit to data for each age group is shown with corresponding R2 values for significant correlations. More negative SNR-50 indicates better speech reception in noise. Higher values of coefficient “B” indicate better frequency resolution. Higher values of coefficient “A” indicate poorer across-frequency intensity resolution.
