This study compared two approaches for measuring speech-recognition thresholds (SRTs): the ASHA (1979) and ASHA (1988) guidelines. The subjects were 30 veterans with impaired hearing. Contrary to prior reports, the ASHA (1979) approach was found to be slightly less time consuming than the ASHA (1988) approach. The ASHA (1979) approach also yielded slightly better pure tone average (PTA)-SRT agreement than the ASHA (1988) approach for two of three generally accepted measures for comparing these tests; the third measure yielded equivalent results. Although statistically significant, the differences between these guidelines in test time and PTA-SRT agreement were small and are considered to be clinically insignificant.
本研究比较了两种测量言语识别阈值（SRT）的方法：美国言语、语言和听力协会（ASHA）1979年和1988年的指南。受试者为30名听力受损的退伍军人。与先前的报告相反，发现ASHA（1979）方法比ASHA（1988）方法耗时略少。对于三种普遍接受的比较这些测试的测量方法中的两种，ASHA（1979）方法在纯音平均听阈（PTA）与SRT的一致性方面也略优于ASHA（1988）方法；第三种测量方法得出了等效结果。尽管在统计学上有显著差异，但这些指南在测试时间和PTA-SRT一致性方面的差异很小，被认为在临床上无显著意义。
