Table 4.
Individual speech understanding performance for all LF CI cutoffs tested for each participant for AzBio sentence recognition in the fixed SNR in the A) bimodal listening configuration and B) bilateral-aided EAS condition. In each table, the participant’s “preferred” LF CI cutoff—for the best-aided EAS condition as indicated by the participants’ reported preferred sound quality—is indicated by shading. In Table B, those scores with an asterisk indicate that the participant’s preferred LF CI cutoff, for sound quality purposes, yielded significantly lower speech understanding as compared to that individual’s own best score based on the upper and lower 95% confidence intervals for AzBio sentence lists administering two 20-sentence lists.
