使用一个原型高频听力计，在8 - 20 kHz范围内的听阈，从240名受试者，年龄从10 - 60岁。获得这些测量值是为了开发8 kHz以上频率的规范数据库，并评估受试者间变异性随年龄的变化。方差分析（ANOVA）显示频率，年龄和性别的显着影响，并显着的频率与年龄的相互作用。敏感性随年龄的变化最大的发生在40至59岁之间。低于约15 kHz，阈值估计的受试者间变异性随着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，而不是与年龄本身有关。当数据转换为dB HL（相对于最年轻的测试组）时，最大听力损失的区域随着年龄的增长而向较低频率移动，并且随着年龄的增长，阈值移动在13 - 17 kHz范围内最大。
Using a prototype high-frequency audiometer, auditory thresholds in the 8- to 20-kHz range were obtained form 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 approximatley 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.
