Abstract	Purpose: Although poorer understanding of speech in noise by listeners who are hearing-impaired (HI) is known not to be directly related to audiometric hearing threshold, "HT" (f), grouping HI listeners with "HT" (f) is widely practiced. In this article, the relationship between consonant recognition and "HT" (f) is 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. (As Provided).
