The availability of a compact disc with a female speaker for clinical use has raised the issue of the equivalence between the female speaker and the previous standard male speaker for assessing the speech reception threshold (SRT). This study evaluated the relationship of two- and three-frequency averages to the SRT for a male speaker on an audio tape and a female speaker on a compact disc in two similar groups of clinic patients, each consisting of 215 ears. There were no significant differences between the SRTs for the two groups, suggesting that the two speakers/recordings are equivalent for clinical purposes. The SRTs from both speakers/recordings were within 6 dB of both the two- and three-frequency averages. There were no significant differences between the SRTs and the three-frequency average.
一张配有女性发音者的供临床使用的光盘的出现，引发了关于在评估言语接受阈（SRT）时女性发音者与先前标准男性发音者之间等效性的问题。本研究在两组相似的临床患者中评估了一盒录音带上男性发音者和一张光盘上女性发音者的双频和三频平均值与SRT之间的关系，每组各有215只耳朵。两组的SRT之间没有显著差异，这表明对于临床目的而言，这两种发音者/录音是等效的。来自两种发音者/录音的SRT均在双频和三频平均值的6分贝范围内。SRT与三频平均值之间没有显著差异。
