Using a prototype high-frequency audiometer, auditory thresholds in the 8- to 20-kHz range were obtained from 240 subjects ranging in age from 10-60 years. These measurements were obtained in interest of developing a normative database for frequencies above 8 kHz, and to evaluate intersubject variability as a function of age. An analysis of variance (ANOVA) revealed significant effects of frequency, age, and sex, and a significant frequency-by-age interaction. The largest changes in sensitivity with age occurred between 40 to 59 years. Below approximately 15 kHz, the intersubject variability of threshold estimates increased as a function of both age and frequency. Further analysis revealed that the age-related changes in variability were related to absolute thresholds rather than to age per se. When data are converted to dB HL (relative to the youngest group tested), the region of maximum hearing loss shifts to lower frequencies with increasing age, and threshold shifts with age are greatest in the 13- to 17-kHz range.
使用一台原型高频听力计，对年龄在10至60岁之间的240名受试者进行了8至20千赫兹范围内的听阈测量。进行这些测量是为了建立一个8千赫兹以上频率的标准数据库，并评估受试者间变异性随年龄的变化情况。方差分析（ANOVA）显示频率、年龄和性别有显著影响，以及频率与年龄的显著交互作用。随年龄增长敏感性变化最大的年龄段在40至59岁之间。在大约15千赫兹以下，阈值估计的受试者间变异性随年龄和频率的增加而增加。进一步分析表明，与年龄相关的变异性变化与绝对阈值有关，而非与年龄本身有关。当数据转换为dB HL（相对于测试的最年轻组）时，最大听力损失区域随年龄增长向低频转移，且在13至17千赫兹范围内，阈值随年龄的变化最大。
