Abstract

Principal component analyses of the better-ear pure-tone audiograms from 201 hearing-impaired children are reported. The analyses show that two components, one measuring degree of hearing loss, the other the slope of the audiogram, account for 86% of the total variability. Two indices are proposed which correspond to the two components, but which have numerically simple coefficients and which, unlike the raw components, are perfectly "clean" measures of the two variables. Since these indices, 11 and 12, still account for 84% of the total audiogram variability, it is suggested that they may provide a quantitative basis for summarizing pure tone audiograms for general use.

摘要

报告了对201名听力受损儿童较好耳纯音听力图进行的主成分分析。分析表明，两个成分，一个测量听力损失程度，另一个测量听力图斜率，占总变异性的86%。提出了两个指数，它们分别对应这两个成分，但系数在数值上简单，并且与原始成分不同，是这两个变量的完全“纯净”的测量指标。由于这两个指数I1和I2仍占听力图总变异性的84%，因此建议它们可为总结纯音听力图以供一般使用提供定量基础。
