本研究的目的是确定听力正常的受试者使用六种线性助听器的语音识别表现与通过仔细推导的发音指数预测的这些助听器的表现之间的一致程度。还调查了助听器平均受试者表现的剩余可变性中有多少可归因于谐波失真。研究发现，预测表现和平均观察表现的差异从未超过8.4 rau（平均= 2.3 rau），并且单独使用的发音指数程序占平均受试者表现差异的90%至94%。
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.
