Importance weighted audibility and the recognition of hearing aid-processed speech.
The purpose of this study was to determine the extent of the agreement between the speech-recognition performance of normally hearing subjects with each of six linear hearing aids and the performance predicted for those aids by a carefully derived articulation index. Also investigated was how much of the remaining variability in average subject performance across hearing aids could be attributed to harmonic distortion. It was found that predicted performance and average observed performance never differed by more than 8.4 rau (mean = 2.3 rau) and that the articulation index procedure used alone accounted for 90 to 94% of the variance in averaged subject performance.
