PURPOSE: Although poorer understanding of speech in noise by hearing-impaired (HI) listeners is known not to be directly related to audiometric threshold [HT (f)], grouping HI listeners with HT (f) is widely practiced. In this study, the relationship between consonant recognition and HT (f) was considered over a range of signal-to-noise ratios (SNRs). METHOD: Confusion matrices (CMs) from 25 HI ears were generated in response to 16 consonant-vowel syllables presented at 6 different SNRs. Individual Differences SCALing (INDSCAL) was applied to both feature-based matrices and CMs in order to evaluate the relationship between HT (f) and consonant recognition among HI listeners. RESULTS: The results showed no predictive relationship between the percent error scores [Pe] and HT (f) across SNRs. The multiple regression models showed that the HT (f) accounted for 39% of the total variance of the slopes of the Pe. Feature-based INDSCAL analysis showed consistent grouping of listeners across SNRs, but not in terms of HT (f). Systematic relationship between measures was also not defined by CM-based INDSCAL analysis across SNRs. CONCLUSIONS: HT (f) did not account for the majority of the variance (39%) in consonant recognition in noise when the complete body of the CM was considered. |
